The Car Modeling DesignFor car modelling, mention the word people often can produce immediately for lenovo in the form of various body, although it is not comprehensive, because car styling is the sum of outside and inside modelling, but had to admit that the appearance of the car is the most intuitive impression of automobile modeling for people. For the automobile modeling design, it covers knowledge engineering technology, art and so on various aspects of the application and market demand, to meet the consumers' taste and functional requirements.Literally what is undeniable is that the car modeling design is derived from the designers of creative expression, by the designer, to many human idea about the car for a reasonable attempt, constantly breakthrough self, challenge themselves. Car modelling design, whether it's like ordinary people use of household car, or royal family use limousine, or a professional driver favorite car, sports car, they all have very obvious differentiation on modelling, the people in the street to see what level of body, the brand, to the natural identity formed certain association of owners, and for different brands of automobile modeling design, which comes from different designers for car design. Car modelling design is also on the technical support of many other disciplines, here I am to have very important influence on development of automobile modeling design of some of the subject part lists are analyze.Since the emergence of the car, bionics started inadvertently used in the design of the model. For automobile modeling, the bionic design in automobile modeling with a unique code to liberate the inherent pattern design of modelling form, interpretation of power, speed, and the symbol of status, wealth, fashion, convey the entire design concept. Nowadays, bionics become guidance and aided automobile modeling design is an important subject, bionic design also gradually become an important means of design, it not only build the people and things, harmonious coexistence between man and nature, man and society, also prompted design found a new form.Bionic design is applied to the various design very early, so see it is not surprising that, in the car on modelling is my understanding of the bionics, it is the nature of some biological characteristics of the advantages of refining of science improving applied to other industries, it is the purpose of pursuing people to draw inspiration from the biological resources, such as car early in the development of a designer to design the "fish" car, maybe at that time did not rise up the subject of bionics, but stylist inadvertently used for fish in the water received by its own size decrease in water resistance and to speed up their swimming this, and apply onto the body modelling design, more typical case is 1952 gm buick brand "fish" type design, surface modeling is very dynamic, because the car interior ministry wide, wide field of vision, both passengers and drivers, inside the body will feel carefree, the affinity of car body itself has an irresistible, should allowstereotyped monotonous straight line in car design, is also a very important breakthrough at the time.There are a lot of examples, such as "viper" is a sports car, as America's most ferocious snake - "viper", has the characteristics of all nature disaster. "Viper" series of models, as a breakthrough point, the appearance of modelling design in particular the sharp front face and the spirit of the headlamps, give a person with terrible ferocity, good at dueling sensory stimulation, like soldiers courageous warrior, always ready to fight to the death, embodies the human eternal pursuit of the meaning of life. Viper, the second generation of 9 models, convey the intrinsic well. Automobile modeling bionic design with "from nature to the nature", as has been the pursuit of goals, the application of natural biological form surface is limited modelling space into endless spiritual awareness, create a bionic form of aesthetic value, to achieve the "personalized" demand and the state of "imitating the nature". Can reference on modelling human nature, The Times on the automobile modeling application development gradually, it seems to me is not only on the auto industry development and progress, is more of a human can live in the actual production of respecting nature, respect nature, from the development of bionics in the automobile modeling design process I can read the industry further development, it is also because modelling are close to the essence of life itself.Automobile modeling design purpose lies in the combination offunction and form aesthetic feeling, to give users in a certain emotional factors influence or impact on the market, on modelling design, different automobile modeling can bring a person different emotional experience, and to convey the designer wants to make people get on a car design.Automobile modeling design is applied art gimmick science express car function, structure and texture, and make people for its beauty. Automobile modeling design must reflect the style of the vehicle, such as streamlined can indicate the car has a higher speed, so as to shape a sporty image in the consumers' mind. Carbon fiber material can reflect the high-tech feeling and lightness of car, has a muscular body form can express powerful and protection of security. Excellent automobile modeling design can make consumers by aesthetic appreciation to deep understanding of its meaning, to produce the desire of the product. This is based on the perceptual technology this is not by many cognitive developed from cognitive psychology on the subject's important role on the automobile modeling design. It is stylist will be collected from the market information, through the analysis of consumer psychology that design more accord with human aesthetic and functional requirements of product evolutionary design, stylist is in perceptual information, consumer psychology and rational constraints (engineering) between coordination.In automobile product development model of "user as the center" in the early stage of the design need to study consumer's perceptual demand, andconsumers to seek in the perceptual demand often from the image of the car. Such as businessman to give reliable partners to form the image of good faith, the car for business occasions, modelling is generally very grave, composed, atmosphere; Racing car, for example, has very obvious streamline on modelling design, in order to display the car performance is strong, can run very fast, with enough instances of racer; Cultural entertainment venue such as car again, the modelling is compared commonly lively, fashion, have individual character, to show the meeting activities and the characteristics of representative. These are the perceptual technology on automobile modeling design is applied to car use and the appreciation of the most common level.Automobile modeling are actually very close to our daily life, on the streets everywhere the family car, taxi, bus, sometimes even see a cable car, luxury cars, sports car, saloon car. We have a lot of focus on automobile brand rather than modelling. But nature sense, any brand of car has its unique style of the modelling, we are to determine the brand car with its shape characteristics, such as seen in the street a lamborghini, its streamline appearance alone, we will be able to determine that it is lamborghini car, this is the car model represented by the car culture connotation. At the end of this course, the reason I chose to automobile modeling design analysis for class papers, but also for any automobile modeling design, as far as I'm concerned, is the designer of some design ideas of cultural interpretation,any design is necessarily comes from life, no experience and observation, can't make the products can be accepted by the public. Automobile modeling is not only the appearance, also is not only a decoration, interior space how to start from the Angle of human nature, and so on these elements are necessarily involve automobile modeling. So this is a worthy art, technology and market coordination aspects of creative achievement, no matter from what Angle to design the vehicle model, the ultimate goal is to continuously improve to meet the needs of users of the product.汽车造型设计对于汽车造型，提到这个词时人们往往能立即产生对于各种车身形态的联想，虽然它并不全面，因为汽车造型是汽车外部和车厢内部造型的总和，但不得不承认的是，汽车的外观的确是人们对于汽车造型的最直观印象。

Bradford: 1993.Vol.ABSTRACT: Ultrasonic ranging technology has wide using worth in many fields, such as the industrial locale, vehicle navigation and sonar engineering. Now it has been used in level measurement, self-guided autonomous vehicles, fieldwork robots automotive navigation, air and underwater target detection, identification, location and so on. So there is an important practicing meaning to learn the ranging theory and ways deeply. To improve the precision of the ultrasonic ranging system in hand, satisfy the request of the engineering personnel for the ranging precision, the bound and the usage, a portable ultrasonic ranging system based on the single chip processor was developed.Keywords: Ultrasound, Ranging System, Single Chip Processor1. IntroductiveWith the development of science and technology, the improvement of people’s standard of living, speeding up the development and construction of the city. Urban drainage system have greatly developed their situation is construction improving. However, due to historical reasons many unpredictable factors in the synthesis of her time, the city drainage system. In particular drainage system often lags behind urban construction. Therefore, there are often good building excavation has been building facilities to upgrade the drainage system phenomenon. It brought to the city sewage, and it is clear to the city sewage and drainage culvert in the sewage treatment system.Co mfort is very important to people’s lives. Mobile robots designed to clear the drainage culvert and the automatic control system Free sewage culvert clear guarantee robots, the robot is designed to clear the culvert sewage to the core. Control system is the core component of the development of ultrasonic range finder. Therefore, it is very important to design a good ultrasonic range finder.2. A principle of ultrasonic distance measurementThe application of AT89C51:SCM is a major piece of computer components are integrated into the chip micro-computer. It is a multi-interface and counting on the micro-controller integration, and intelligence products are widely used in industrial automation. and MCS-51 microcontroller is a typical and representative.Microcontrollers are used in a multitude of commercial applications such as modems, motor-control systems, air conditioner control systems, automotive engine and among others. The high processing speed and enhanced peripheral set of these microcontrollers make them suitable for such high-speed event-based applications. However, these critical application domains also require that these microcontrollers are highly reliable. The high reliability and low market risks can be ensured by a robust testing process and a proper tools environment for the validation of these microcontrollers both at the component and at the system level. Intel Plaform Engineering department developed an object-oriented multi-threaded test environment for the validation of its AT89C51 automotive microcontrollers. The goals of this environment was not only to provide a robust testing environment for the AT89C51 automotive microcontrollers, but to develop an environment which can be easily extended and reused for the validation of several other future microcontrollers. The environment was developed in conjunction with Microsoft Foundation Classes(AT89C51).1.1 Features* Compatible with MCS-51 Products* 2Kbytes of Reprogrammable Flash MemoryEndurance: 1,000Write/Erase Cycles* 2.7V to 6V Operating Range* Fully Static operation: 0Hz to 24MHz* Two-level program memory lock* 128x8-bit internal RAM* 15programmable I/O lines* Two 16-bit timer/counters* Six interrupt sources*Programmable serial UART channel* Direct LED drive output* On-chip analog comparator* Low power idle and power down modes1.2 DescriptionThe AT89C2051 is a low-voltage, high-performance CMOS 8-bit microcomputer with 2Kbytes of flash programmable and erasable read only memory (PEROM). The device is manufactured using Atmel’s high density nonvolatile memory technology and is compatible with the industry standard MCS-51 instruction set and pinout. By combining a versatile 8-bit CPU with flash on a monolithic chip, the Atmel AT89C2051 is a powerful microcomputer which provides a highly flexible and cost effective solution to many embedded control applications.The AT89C2051 provides the following standard features: 2Kbytes of flash,128bytes of RAM, 15 I/O lines, two 16-bit timer/counters, a five vector two-level interrupt architecture, a full duplex serial port, a precision analog comparator, on-chip oscillator and clock circuitry. In addition, the AT89C2051 is designed with static logicfor operation down to zero frequency and supports two software selectable power saving modes. The idle mode stops the CPU while allowing the RAM, timer/counters, serial port and interrupt system to continue functioning. The power down mode saves the RAM contents but freezer the oscillator disabling all other chip functions until the next hardware reset.1.3 Pin Configuration1.4 Pin DescriptionVCC Supply voltage.GND Ground.Prot 1Prot 1 is an 8-bit bidirectional I/O port. Port pins P1.2 to P1.7 provide internal pullups. P1.0 and P1.1 require external pullups. P1.0 and P1.1 also serve as the positive input (AIN0) and the negative input (AIN1), respectively, of the on-chip precision analog comparator. The port 1 output buffers can sink 20mA and can drive LED displays directly. When 1s are written to port 1 pins, they can be used as inputs. When pins P1.2 to P1.7 are used as input and are externally pulled low, they will source current (IIL) because of the internal pullups.Port 3Port 3 pins P3.0 to P3.5, P3.7 are seven bidirectional I/O pins with internal pullups. P3.6 is hard-wired as an input to the output of the on-chip comparator and is not accessible as a general purpose I/O pin. The port 3 output buffers can sink 20mA. When 1s are written to port 3 pins they are pulled high by the internal pullups and can be used as inputs. As inputs, port 3 pins that are externally being pulled low will source current (IIL) because of the pullups.Port 3 also serves the functions of various special features of the AT89C2051 as listed below.1.5 Programming the FlashThe AT89C2051 is shipped with the 2 Kbytes of on-chip PEROM code memory array in the erased state (i.e., contents=FFH) and ready to be programmed. The code memory array is programmed one byte at a time. Once the array is programmed, to re-program any non-blank byte, the entire memory array needs to be erased electrically.Internal address counter: the AT89C2051 contains an internal PEROM address counter which is always reset to 000H on the rising edge of RST and is advanced applying a positive going pulse to pin XTAL1.Programming algorithm: to program the AT89C2051, the following sequence is recommended.1. power-up sequence:Apply power between VCC and GND pins Set RST and XTAL1 to GNDWith all other pins floating , wait for greater than 10 milliseconds2. Set pin RST to ‘H’ set pin P3.2 to ‘H’3. Apply the appropriate combination of ‘H’ or ‘L’ logic to pins P3.3, P3.4, P3.5,P3.7 to select one of the programming operations shown in the PEROM programming modes table.To program and Verify the Array:4. Apply data for code byte at location 000H to P1.0 to P1.7.5.Raise RST to 12V to enable programming.5. Pulse P3.2 once to program a byte in the PEROM array or the lock bits. The byte-write cycle is self-timed and typically takes 1.2ms.6. To verify the programmed data, lower RST from 12V to logic ‘H’ level and set pins P3.3 to P3.7 to the appropriate levels. Output data can be read at the port P1 pins.7. To program a byte at the next address location, pulse XTAL1 pin once to advance the internal address counter. Apply new data to the port P1 pins.8. Repeat steps 5 through 8, changing data and advancing the address counter for the entire 2 Kbytes array or until the end of the object file is reached.9. Power-off sequence: set XTAL1 to ‘L’ set RST to ‘L’Float all other I/O pins Turn VCC power off2.1 The principle of piezoelectric ultrasonic generatorPiezoelectric ultrasonic generator is the use of piezoelectric crystal resonators to work. Ultrasonic generator, the internal structure as shown, it has two piezoelectric chip and a resonance plate. When it’s two plus pulse signal, the frequency equal to the intrinsic piezoelectric oscillation frequency chip, the chip will happen piezoelectric resonance, and promote the development of plate vibration resonance, ultrasound is generated. Conversely, it will be for vibration suppression of piezoelectric chip, the mechanical energy is converted to electrical signals, then it becomes the ultrasonic receiver.The traditional way to determine the moment of the echo’s arrival is based on thresholding the received signal with a fixed reference. The threshold is chosen well above the noise level, whereas the moment of arrival of an echo is defined as the first moment the echo signal surpasses that threshold. The intensity of an echo reflecting from an object strongly depends on the object’s nature, size and distance from the sensor. Further, the time interval from the echo’s starting point to the moment when it surpasses the threshold changes with the intensity of the echo. As a consequence, a considerable error may occur even two echoes with different intensities arriving exactly at the same time will surpass the threshold at different moments. The stronger one will surpass the threshold earlier than the weaker, so it will be considered as belonging to a nearer object.2.2 The principle of ultrasonic distance measurementUltrasonic transmitter in a direction to launch ultrasound, in the moment to launch the beginning of time at the same time, the spread of ultrasound in the air, obstacles on his way to return immediately, the ultrasonic reflected wave received by the receiverimmediately stop the clock. Ultrasound in the air as the propagation velocity of 340m/s, according to the timer records the time t, we can calculate the distance between the launch distance barrier(s), that is: s=340t / 23. Ultrasonic Ranging System for the Second Circuit DesignSystem is characterized by single-chip microcomputer to control the use of ultrasonic transmitter and ultrasonic receiver since the launch from time to time, single-chip selection of 875, economic-to-use, and the chip has 4K of ROM, to facilitate programming.3.1 40 kHz ultrasonic pulse generated with the launchRanging system using the ultrasonic sensor of piezoelectric ceramic sensorsUCM40, its operating voltage of the pulse signal is 40kHz, which by the single-chip implementation of the following procedures to generate.puzel: mov 14h, # 12h; ultrasonic firing continued 200msHere: cpl p1.0; output 40kHz square wavenop;nop;nop;djnz 14h, here;retRanging in front of single-chip termination circuit P1.0 input port, single chip implementation of the above procedure, the P1.0 port in a 40kHz pulse output signal, after amplification transistor T, the drive to launch the first ultrasonic UCM40T, issued 40kHz ultrasonic pulse, and the continued launch of 200ms. Ranging the right and the left side of the circuit, respectively, then input port P1.1 and P1.2, the working principle and circuit in front of the same location.3.2 Reception and processing of ultrasonicUsed to receive the first launch of the first pair UCM40R, the ultrasonic pulse modulation signal into an alternating voltage, the op-amp amplification IC1A and after polarization IC1B to IC2. IC2 is locked loop with audio decoder chip LM567, internal voltage-controlled oscillator center frequency of f0=1/1.1R8C3, capacitor C4 determinetheir target bandwidth. R8-conditioning in the launch of the high jump 8 feet into a low-level, as interrupt request signals to the single-chip processing.Ranging in front of single-chip termination circuit output port INT0 interrupt the highest priority, right or left location of the output circuit with output gate IC3A access INT1 port single-chip, while single-chip P1.3 and P1.4 received input IC3A, interrupted by the process to identify the source of inquiry to deal with, interrupt priority level for the first left right after. Part of the source code is as follows:Receivel: push pswpush accclr ex1; related external interrupt 1jnb p1.1, right; P1.1 pin to 0, ranging from right to interrupt service routine circuitjnb p1.2, left; P1.2 pin to 0, to the left ranging circuit interrupt service routinereturn: SETB EX1; open external interrupt 1pop accpop pswretiright: …; right location entrance circuit interrupt service routineAjmp Returnleft: …; left ranging entrance circuit interrupt service routineAjmp Return3.3 The calculation of ultrasonic propagation timeWhen you start firing at the same time start the single-chip circuitry within the timer T0, the use of timer counting function records the time and the launch of ultrasonic reflected wave received time. When you receive the ultrasonic reflected wave, the receiver circuit output a negative jump in the end of INT0 or INT1 interrupt request generates a signal, single-chip microcomputer in response to external interrupt request, the implementation of the external interrupt service subroutine, read the time difference, calculating the distance. Some of its source code is as follows:RECEIVE0: PUSH PSWPUSH ACCCLR EX0; related external interrupt 0MOV R7, TH0; read the time valueMOV R6, TL0CLR CMOV A, R6SUBB A, #0BBH; calculate the time differenceMOV 31H, A; storage resultsMOV A, R7SUBB A, # 3CHMOV 30H, ASETB EX0; open external interrupt 0\POP ACCPOP PSWRETIFor a flat target, a distance measurement consists of two phases: a coarse measurement and a fine measurement:Step 1: Transmission of one pulse train to produce a simple ultrasonic wave.Step 2: Changing the gain of both echo amplifiers according to equation, until the echo is detected.Step 3: Detection of the amplitudes and zero-crossing times of both echoes.Step 4: Setting the gains of both echo amplifiers to normalize the output at, say 3 volts. Setting the period of the next pulses according to the: period of echoes. Setting the time window according to the data of step 2.Step 5: Sending two pulse trains to produce an interfered wave. Testing the zero-crossing times and amplitudes of the echoes. If phase inversion occurs in the echo, determine to otherwise calculate to by interpolation using the amplitudes near the trough. Derive t sub m1 and t sub m2.Step 6: Calculation of the distance y using equation.4、The ultrasonic ranging system software designSoftware is divided into two parts, the main program and interrupt service routine. Completion of the work of the main program is initialized, each sequence of ultrasonic transmitting and receiving control.Interrupt service routines from time to time to complete three of the rotation direction of ultrasonic launch, the main external interrupt service subroutine to read the value of completion time, distance calculation, the results of the output and so on.5、ConclusionsRequired measuring range of 30cm-200cm objects inside the plane to do a number of measurements found that the maximum error is 0.5cm, and good reproducibility. Single-chip design can be seen on the ultrasonic ranging system has a hardware structure is simple, reliable, small features such as measurement error. Therefore, it can be used not only for mobile robot can be used in other detection system.Thoughts: As for why the receiver do not have the transistor amplifier circuit, because the magnification well, integrated amplifier, but also with automatic gain control level, magnification to 76dB, the center frequency is 38k to 40k, is exactly resonant ultrasonic sensors frequency.6、Parking sensor6.1 Parking sensor introductionReversing radar, full name is "reversing the anti-collision radar, also known as" parking assist device, car parking or reversing the safety of assistive devices, ultrasonic sensors(commonly known as probes), controls and displays (or buzzer)and other components. To inform the driver around the obstacle to the sound or a moreintuitive display to lift the driver parking, reversing and start the vehicle around tovisit the distress caused by, and to help the driver to remove the vision deadends and blurred vision defects and improve driving safety.6.2 Reversing radar detection principleReversing radar, according to high-speed flight of the bats in thenight, not collided with any obstacle principles of design anddevelopment. Probe mounted on the rear bumper, according to different price and brand, the probe only ranging from two, three, four, six, eight,respectively, pipe around. The probe radiation, 45-degree angle up and downabout the search target. The greatest advantage is to explore lower than the bumper of the driver from the rear window is difficult to see obstacles, and the police, suchas flower beds, children playing in the squatting on the car.Display parking sensor installed in the rear view mirror, it constantlyremind drivers to car distance behindthe object distance to the dangerous distance, the buzzer starts singing, allow the driver to stop. When the gear lever linked into reverse gear, reversing radar, auto-start the work, the working range of 0.3 to 2.0 meters, so stop when the driver was very practical. Reversing radar is equivalent to an ultrasound probe for ultrasonic probe can be divided into two categories: First, Electrical, ultrasonic, the second is to use mechanical means to produce ultrasound, in view of the more commonly used piezoelectric ultrasonic generator, it has two power chips and a soundingboard, plus apulse signal when the poles, its frequency equal to the intrinsic oscillation frequency of the piezoelectric pressure chip will be resonant and drivenby the vibration of the sounding board, the mechanical energy into electrical signal, which became the ultrasonic probe works. In order to better study Ultrasonic and use up, people have to design and manufacture of ultrasonic sound, the ultrasonic probe tobe used in the use of car parking sensor. With this principle in a non-contactdetection technology for distance measurement is simple, convenient and rapid, easyto do real-time control, distance accuracy of practical industrial requirements. Parking sensor for ranging send out ultrasonic signal at a givenmoment, and shot in the face of the measured object back to the signal wave, reversing radar receiver to use statistics in the ultrasonic signal from the transmitter to receive echo signals calculate the propagation velocity in the medium, which can calculate the distance of the probe and to detect objects.6.3 Reversing radar functionality and performanceParking sensor can be divided into the LCD distance display, audible alarm, and azimuth directions, voice prompts, automatic probe detection function is complete, reversing radar distance, audible alarm, position-indicating function. A good performance reversing radar, its main properties include: (1) sensitivity, whether theresponse fast enough when there is an obstacle. (2) the existence of blind spots. (3) detection distance range.6.4 Each part of the roleReversing radar has the following effects: (1) ultrasonic sensor: used tolaunch and receive ultrasonic signals, ultrasonic sensors canmeasure distance. (2) host: after the launch of the sine wave pulse to the ultrasonic sensors, and process the received signal, to calculate the distance value, the data and monitor communication. (3) display or abuzzer: the receivinghost from the data, and display the distance value and provide differentlevels according to the distance from the alarm sound.6.5 Cautions1, the installation height: general ground: car before the installation of 45 ~55: 50 ~ 65cmcar after installation. 2, regular cleaningof the probe to prevent the fill. 3, do not use the hardstuff the probe surface cover will produce false positives or ranging allowed toprobe surface coverage, such as mud. 4, winter to avoid freezing. 5, 6 / 8 probe reversing radar before and after the probe is not free to swap may cause the ChangMing false positive problem. 6, note that the probe mounting orientation, in accordance with UP installation upward. 7, the probe is not recommended to install sheetmetal, sheet metal vibration will cause the probe resonance, resulting in false positives.超声测距系统设计原文出处：传感器文摘布拉福德：1993年超声测距技术在工业现场、车辆导航、水声工程等领域具有广泛的应用价值，目前已应用于物位测量、机器人自动导航以及空气中与水下的目标探测、识别、定位等场合。

整车总布置设计流程(Whole vehicle layout design flow)

整车总布置设计流程（Whole vehicle layout design flow）In this paper, the contribution of Yu Cheng Cheng RiverDOC documents may experience poor browsing on the WAP side.

Below we discuss the new car overall design layout method. First of all, the overall layout of the design staff to determine the design concept, that is, a clear design task book. In the overall design process, it is necessary to determine the main vehicle size parameters, the main performance parameters, quality parameters and the basic types of the system assembly, select the engine and tire models, and so on. These are preliminary layout and conceptual design phases, that is, the Layout phase. With the design work being carried out, the body parts are gradually selected or the design is completed step by step, and then the fine design phase is entered, that is called the precise arrangement and the virtual assembly inspection stage, that is, the packaging stage."Z* L% P P9 F4 x+ j# I/ X"The preliminary determination of these parameters is the first step in the overall layout design of the vehicle. To determine the size and parameters can not rely on the accurate calculation, according to the general plan and the performance of new product development requirements, based on a large number of car market investigation and statistical analysis on the reference of domestic and foreign similar models, select the corresponding prototype as identified parameters. At the same time should also pay attention to the parameters to comply with the requirements of various regulations and standards.Forum / 3D network technology _'W 3 C6 K 5 |% @ (E5 H & U3 xThen, according to the basic dimensions and design points of the general layout design, a variety of automobile shape effect diagrams and models are designed by the styling designer, and then the design of the vehicle interior facilities is determined. Selection of the best programs, and make the overall designer vehicle layout design, determine the overall vehicle parameters, for clay modeling, finalized after the general arrangement by the designer with the overall vehicle layout design. The overall vehicle design parameters mainly include: total length and width, total height; wheelbase, front suspension, rear suspension, wheels (front and rear wheels); the angle of departure, close to the minimum ground clearance angle, etc.. Generally speaking, with the determination of the overall design parameters, the main size parameters of the body can also be initially determined. With the main dimensions of the general design parameters and the vehicle body, the otherdimensions in the layout design parameters should be gradually specific, and make it meet the size requirements; on the other hand, initially set the vehicle and main body size parameters in the layout design can get the deepening of the revisions, and eventually was determined. The total vehicle arrangement established to control the size of the car length, width and height, wheelbase, wheel, axle load distribution and water tank, powertrain, front and rear axle, transmission shaft and wheel contour size and position, then the reference data as a reference of similar models.The designer can initially determine the length, position and angle of front and rear windows, front engine and rear suspension cover height, floor level, cowl position, seat arrangement, internal space size, control the position of the steering wheel angle and steering mechanism and pedal position and so on. In short, the layout design of engine, driving device, suspension assembly, electrical equipment, spare parts, fuel tank, vehicle interior assembly and parts of the location, size, and the main technical parameters of body size and body trunk interior space, design process determined in full body styling requirements.E& x- R/: @ * _! V8 OThe ultimate goal is to arrange all the assembly and components in a limited body size, and to maximize the indoor space and improve the market competitiveness of the product.The overall layout of the vehicle has a relationship with the body, chassis, and coordinate each other. Often cross over andover again. This coordination requires designers' wisdom and experience. In this process, a great deal of effort and time are spent on the correction of data, which requires the whole design team to do the preparatory work in advance. Due to the design of a large part of the design is improved based on the original reference models on, even if is to develop a new model, not to design all the parts, but the use of large numbers of parts used to reduce cost, reduce risk. However, in order to make the product appear in front of the user in a new image, the body parts often need to be redesigned, and the parameters of the known engine and chassis components are arranged in the whole vehicle.% K; `2, g%, C6, M9, yTherefore, we have always arranged in the design method, integrated two design ideas, that is, chassis and body simultaneously design.A new car design starts with car styling. Modeling work includes drawing renderings, making models and so on. Previous car styling was entirely dependent on hand making. After making the outline of the car by hand sketching, the final scheme is determined by making a number of clay models. Now, car stylists can use their advanced graphics processing software to express their intentions quickly. Through the effect diagram, the 3D surface model is directly modeled by the 3D surface software, and the NC machining model is directly carried out after the fairing of the surface, so that the model is maximally consistent with the designer's intention.D, CAD, machinery, technology, automotive, CA TIA, PR o/e, UG inven, tor so, lidedg e, soli dworks, CAXA, time and space, Zhenjiang 'Z & G% _ + B* K + A8 f r #In other work carried out at the same time, the whole layout has begun initial tentative plan, body structure modeling, section selection, chassis parameters, structure selection and maturation. Modeling work and vehicle structure determination are interrelated and interactive. Before the whole assembly or by computer graphic design drawing program to modify the manual, time-consuming, vehicle layout is now used by Dave software, parameter modification, visual image and increase efficiency. The main contents of the overall design include the hard point of the whole vehicle. The so-called "hard point" means the position or shape that can not be changed or forcibly determined in the design of the automobile,It can be a hole, a plane or a section of curved surface and so on, the whole vehicle meets the national standard inspection report preparation, is used in the manufacture enterprise product description document compilation, as well as the entire vehicle assembly inspection. The previous vehicle assembly inspection can only be carried out in the prototype trial, and now the assembly can be checked after assembly of the 3D digital model of the parts, and the problem can be found as soon as possible.

摘要本文主要研究轻型汽车前独立悬架的设计分析方法以及轮胎磨损与悬架运动、前轮定位参数的关系。

首先对双横臂独立悬架的各主要组成部件如减振器的选型设计、横向稳定杆的设计校核、扭杆弹簧设计以及对双横臂式和麦弗逊式独立悬架的运动进行了分析，提出了相应的计算方法，编制了一套具有一定实用价值的前独立悬架设计分析软件。

并且采用前轮定位仪，进行了实验验证。

论文对双横臂独立悬架参数提出以减小轮胎磨损为优化目标，进行了优化设计。

提出了通过优选、调整悬架初始位置状态，以及优化确定转向横拉杆断开点位置的方法，来减小轮胎磨损。

同时采用正交实验的方法分析了双横臂独立悬架各结构参数和安装参数对悬架性能和轮胎磨损的影响，确定出最大的影响因素及次要因素。

然后从轮胎模型入手分析前轮定位参数同轮胎磨损的关系。

以轮胎磨损能量作为评价指标，选取刷子轮胎模型，对轮胎在稳态纵滑状态下、稳态纵滑侧偏状态下和边界条件下的轮胎磨损进行了分析研究，确定了量化模型。

并以轮胎侧偏角为中间变量，建立了前轮定位参数同轮胎磨损之间关系的数学模型，进行了计算机仿真计算。

从而可对悬架进行进一步的优化设计，以减小对轮胎磨损的影响，提高车辆的行驶性能和使用经济性。

简单的说，它是车身与路面之见的桥梁。

悬架的行程涉及到悬浮于车轮之上的车架，传动系的相对位置。

就像横跨于旧金山海湾之上的金门大桥，它连接了海湾两侧。

去掉汽车上的悬架就像是你做一次冷水潜泳通过海湾一样，你可以平安的渡过整个秋天，但会疼痛会持续几周之久。

想想滑板吧！它直接接触路面你可以感受到每一块砖，裂隙及其撞击。

附录 1汽车车身总布置采取以人为中心的设计思想，尤其是在轿车设计中，确保驾驶员与乘员的舒适性、居住性、上下车方便性、安全性以及驾驶员的操纵方便性和视野性等其应遵循一定的设计原则：外部尺寸尽量小、内部空间尽量大、满足各项功能要求、满足人机工程学要求、满足标准法规及技术条件要求。

人机工程学是上世纪50年代发展起来的一门新学科。

它以人-机关系为研究的对象，以实测、统计、分析为基本的研究方法，是一种描述如何塑造适宜人的工作环境的科学。

具体到产品开发，就是在产品的设计和制造方面要按照人体的生理解剖功能量身定做，更加适合于人体的工作效能。

今天的汽车要追求“人车合一”，就是设计汽车的目标要以人为本，围绕人的需求而建造。

要使人驾乘汽车感到舒适、方便和不易疲劳，这就是汽车人机工程学的目的。

汽车设计以总体布置为核心，而轿车总体布置又是从车厢开始的。

为此，要利用能表述人体形状的标准模型作为准绳来安排驾驶舱各个部件位置。

例如驾驶员的位置，从脚踩油门踏板上算起，身材高大者要比身材矮小者靠后坐，这决定了驾驶座椅后移的位置；身材矮小者要比身材高大者靠前坐，这决定了座椅前移的位置。

手臂长度与腿相比是较短的，当座椅后移时可能手触及不到仪表板，这就有了一个范围限制。

例如以百分位人群来划分，假设第5个百分位的女子身高为1.47米，而第95个百分位的男子身高为1.82米，对于固定踏板的布置，工程师就只考虑5%的矮小女子和95%高大男子的手臂触及范围。

做出仪表板的可接触的衡量，通常以高大男人的手臂长为一个决定性准则，即以伸展的手臂运动，在水平及垂直方向上各绘出一个圆弧线，近似描绘出一个半圆形空间去安排座椅、仪表、方向盘、踏板、变速杆、中控板控制旋钮等零部件的位置及相互的距离尺寸。

人机工程学,在美国称之为人类工程学(Human Engineering)、人因工程学(Human Factors Engineering)，在欧洲有人称之为功效学(Ergonomics)，日本称之为人间工学。

SLP ANALYSISLan Xiuju(Institute of Industrial Engineering, Zhejiang University of Technology)Abstract: This paper uses the method of SLP to systematically analyze one enterprise's existing facility layout situation and presents an optimization scheme to reach the goal of reducing logistics cost.Key words: SLP; Value Engineering; Optimization layout; Logistics1 IntroductionBecause of the fierce compel situation enterprises are facing, how to reduce cost effectively, quicken technology improvement, strengthen the ability of competition.2 The Method of SLP and Production Logistics OptimizationFacility layout, on the basis of the functions the system should fulfill is to systematically design all facilities, personnel and investment in the system. Its key content 15 the design of the factory, shops, and facilities and so on. Its goal is to make the logistics route rational, that is, to enhance the whole production system's profit by changing or modulating the production logistics.2.1 The logistics analysis of the metalworking shopMetalworking shop is the processing center of this enterprise. Processing techniques are various with the different types of parts. There are 34 types of parts need to be processed perennial. The first step of design is the detailed analysis of processing techniques of the parts. Take the back moulding board for example (showed in Table l).2.2 Draw location interrelated figure of all work unitsIn metalworking shop, the transfer of the size of the logistics amount is themost important thing to consider, that is, effects of other things can be ignored，So we make propinquity table (Table 6) only according to the work units' logistics interrelated table(Table 5), without taking the non-logistics Interrelated table into account.3 ConclusionsSo for the manufacturing, during the complex pressing process, the first step to reduce the product cost is to optimize facilities layout pattern inside the enterprise. SLP is undoubted an effective method to solve this problem.AcknowledgmentsThe author express sincere thanks to the National Natural Science Foundation of Zhejiang Province for the financial support under the grant number No.Y604305.References[1] Lan Xiuju，Wang Yaliang.
