MK7-3型阻拦装置定长冲跑控制阀结构特点及控制规律
MK7-3型阻拦装置定长冲跑控制阀结构特点及控制规律MK7-3型阻拦装置定长冲跑控制阀是一种用于飞机起落架的阻拦装置，它主要可完成飞机起落架的抬起和放下，并且可以精确控制飞机行进的力度和速度。
其结构特点和控制规律如下。
1. 结构特点MK7-3型阻拦装置定长冲跑控制阀采用的是液压控制系统，主要由定长冲跑控制阀、三通阀、单向阀、减压阀、液压缸与液压泵组成。
定长冲跑控制阀具有精密密封性，通过开关控制，可以实现准确的冲跑长度和速度控制。
在起落架抬升时，阀门关闭隐藏在机体内部，从而防止起落架掉落。
当起落架降落到一定高度时，阀门会打开，从而实现起落架下降。
三通阀的作用是控制液压泵的流向，从而控制液压油向上油缸和下油缸的流动方向。
单向阀可防止液压油倒回液压泵，从而保证环路的稳定性。
减压阀可根据系统的压力，调节起落架上下的力度和速度，从而保证起落架的安全性。
液压缸是起落架的主要载荷，它能够承受飞机起飞和降落时的大荷载，并提供足够的支撑力。
液压泵是装置的动力源，它通过内部的液压传动系统，来为整个装置提供足够的液压动力。
2. 控制规律MK7-3型阻拦装置定长冲跑控制阀的控制规律主要是通过周期性开关来实现的。
在起落架运动过程中，控制阀的开启和关闭决定了起落架的运动速度和力度。
开关的控制信号是通过飞机上的电路系统来控制的。
在起落过程中，控制阀的关闭可以阻止起落架下降，从而确保起落架的稳定性。
当飞机降落时，控制阀会打开，以保证起落架的缓慢下降，从而避免起落架的损坏。
同时，控制阀的周期性开关还可以调节起落架上下的力度和速度，从而使起落架运动更加稳定流畅，确保飞机起飞和降落的安全性。
综上所述，MK7-3型阻拦装置定长冲跑控制阀具有结构紧凑、性能优良、控制灵活、可靠性高等特点，它在飞机起落架的控制方面发挥着关键作用。
通过不断的技术创新和优化，该装置的性能和安全性将不断提高，为飞机的起降提供更加稳定可靠的保障。

交流220 V同步方式通信电路的灯光控制系统
交流220 V同步方式通信电路的灯光控制系统引言直流电的三线控制方式由于线路简单、成本低，广泛用于各种照明系统的控制场合[1，2]，但交流系统中无法提供稳定的参考点[3]，实际应用中通常使用电力线载波通信方式或无线通信方式进行控制，因此存在电路复杂、可靠性低、待机功耗较大、维护难等问题[4]。
为此，本文提出与交流电50 Hz同步方式工作的教室灯光控制系统，这种电路采用三线工作方式，分别为2根220 V交流电源线和一根公用信号线，主机和分机只通过一根公用信号线传送信号。
1 通信电路工作原理设计交流220V同步方式工作的通信电路由一个主机和N个分机组成，可进行双向通信，主机呼叫分机后发送各种操作命令，分机响应后发送本机的状态。
1.1 主机和分机的参考点设计图1为主机和分机之间形成参考地的电路示意图。
山西省日前创新市场化机制，引入中交疏浚（集团）股份有限公司作为战略投资方，组建汾河流域投资公司，统筹项目资金，以市场化方式满足工程建设需求，对汾河进行全流域系统治理。
图1 参考地的形成电路Fig.1 Ground formation circuitR0为线路的等效电阻，R1和R2保证交流电的整个周期中整流桥D1、D2始终处于微导通状态。
当正半周时L线为正极性N线为负极性，整流桥D1的D11、D13导通，整流桥D2的D21、D23导通，A点经过D13、R0、D23连接到B点，当负半周时L线为负极性N线为正极性，整流桥D1的D12、D14导通，整流桥D2的D22、D24导通，A点经过D14、R0、D24连接到B点。
因此不管是正半周还是负半周A点与B点之间的电压UAB取决于式(1)，式中i为线上的交流电流，UD为整流桥中每个二极管的正向压降。
UBA=|iR0+UD|-UD=|iR0|(1)可知整流桥D1、D2导通时压降互相抵消。
由于每个集中控制区的线路电阻较小，电流分布也是离散方式，因此最远的2个装置之间的电压UBA可以控制在30 V以内。

During normal operation, the inter-nal N-channel power MOSFET is turned on each cycle when the oscillator sets an internal RS latch and would be turned off when an internal current comparator (ICMP) resets the latch. The peak inductor current at which ICMP resets the RS latch is controlled by the voltage on the COMP pin, which is the output of the error amplifier (EAMP). An external resistive divider connected between VOUT and ground allows the EAMP to receive an output feedback voltage VFBat FB pin. When the load currentincreases, it causes a slight decrease in VFBrelative to the 0.92V reference, which in turn causes the COMP volt-age to increase until the average inductor current matches the new load current.VIN Power-On-Reset (POR) and EN Under-voltage LockoutThe APW7302B keep monitoring the voltage on VIN pin to prevent wrong logic operations which may occur when VIN voltage is not high enough for the internal control circuitry to operate. The VIN POR has a rising threshold of 4.1V (typical) with 0.5V of hysteresis.An external under-voltage lockout (UVLO) is sensed at the EN pin. The EN UVLO has a rising threshold of 2.5V with 0.2V of hysteresis. The EN pin should be connected a resistor divider from VIN to EN.After the VIN and EN voltages exceed their respective voltage thresholds, the IC starts a start-up process and then ramps up the output voltage to the setting of output voltage.Over-Temperature Protection (OTP)The over-temperature circuit limits the junction tempera-ture of the APW7302B. When the junction temperatureexceeds TJ= +160o C, a thermal sensor turns off the power MOSFET, allowing the devices to cool. The thermal sen-sor allows the converter to start a start-up process and regulate the output voltage again after the junction tem-perature cools by 50o C.The OTP is designed with a 50o C hysteresis to lower the average TJduring continuous thermal overload conditions, increasing lifetime of the lC.Current-Limit ProtectionThe APW7302B monitors the output current, flowing through the N-Channel power MOSFET, and limits the IC from damages during overload, short-circuit and over-voltage conditions.Frequency FoldbackThe foldback frequency is controlled by the FB voltage. When the FB pin voltage is under 0.6V, the frequency of the oscillator will be reduced to 110kHz. This lower fre-quency allows the inductor current to safely discharge, thereby preventing current runaway. The oscillator’s fre-quency will switch to its designed rate when the feedback voltage on FB rises above the rising frequency foldback threshold (0.6V, typical) again.Over-Voltage ProtectionThe over-voltage function monitors the output voltage by FB pin. When the FB voltage increase over 120% of the reference voltage, the over-voltage protection compara-tor will force the low-side MOSFET gate driver high. This action actively pulls down the output voltage. As soon as the output voltage is within regulation, the OVP compara-tor is disengaged. The chip will restore its normal operation.Enable / ShutdownDriving EN to ground places the APW7302B in shutdown. When in shutdown, the internal power MOSFET turns off, all internal circuitry shuts down.Application InformationSetting Output VoltageInductor Capacitor Selectionwhere D is the duty cycle of the power MOSFET .For a through hole design, several electrolytic capacitors may be needed. For surface mount designs, solid tanta-lum capacitors can be used, but caution must be exer-cised with regard to the capacitor surge current rating.)A ()D 1(D I I OUT RMS ⋅−×=)V (ESR I V OUT ⋅×∆=∆OUTOSC COUT C F 8IV ××∆=∆The regulated output voltage is determined by:Use small ceramic capacitors for high frequency decoupling and bulk capacitors to supply the surge cur-rent needed each time the N-channel power MOSFET (Q1) turns on. Place the small ceramic capacitors physi-cally close to the VIN and between the VIN and GND.The important parameters for the bulk input capacitor are the voltage rating and the RMS current rating. For reliable operation, select the bulk capacitor with voltage and current ratings above the maximum input voltage and largest RMS current required by the circuit. The capacitor voltage rating should be at least 1.25 times greater than the maximum input voltage and a voltage rating of 1.5times is a conservative guideline. The RMS current (IRMS)of the bulk input capacitor is calculated as the following equation:An output capacitor is required to filter the output and sup-ply the load transient current. The filtering requirements are the function of the switching frequency and the ripple current (DI). The output ripple is the sum of the voltages,having phase shift, across the ESR and the ideal output capacitor. The peak-to-peak voltage of the ESR is calcu-ated as the following equations:)V ()R R 1(92.0VOUT 21⋅+×=To prevent stray pickup, please locate resistors R1 and R2 close to APW7302B.ESRI V LF )D 1(V I V V D ESR OSC OUT INOUT ×∆=−=∆=××The peak- to-peak voltage of the ideal output capacitor iscalculated as the following equations:For the applications using bulk capacitors, the ∆V COUT is much smaller than the V ESR and can be ignored. Therefore,the AC peak-to-peak output voltage(∆V OUT ) is shown below:Output Capacitor SelectionFor the applications using bulk capacitors, the V ESR is much smaller than the ∆V COUT and can be ignored.Therefore, the AC peak-to-peak output voltage(∆V OUT ) is to ∆V COUT .Figure 1. Converter WaveformsI OUTVLXI LI Q1I COUTI OUTV OUT (1) (2) (3) (4) (5)INV OUTApplication Information(Cont.)Output Capacitor Selection (Cont.)The load transient requirements are the function of the slew rate (di/dt) and the magnitude of the transient load urrent. These requirements are generally met with a mix of capacitors and careful layout. High frequency ca-pacitors initially supply the transient and slow the current load rate seen by the bulk capacitors. The bulk filter ca-pacitor values are generally determined by the ESR (Effective Series Resistance) and voltage rating require-ments rather than actual capacitance requirements.High frequency decoupling capacitors should be placed as close to the power pins of the load as physically possible. Be careful not to add inductance in the circuit board wiring that could cancel the usefulness of these low inductance components. An aluminum electrolytic capacitor’s ESR value is related to the case size with lower ESR available in larger case sizes. However, the Equiva-lent Series Inductance (ESL) of these capacitors increases with case size and can reduce the usefulness of the ca-pacitor to high slew-rate transient loading.The operating frequency and inductor selection are inter-related in that higher operating frequencies permit the use of a smaller inductor for the same amount of inductorripple current. However, this is at the expense of efficiency due to an increase in MOSFET gate charge losses. The equation (2) shows that the inductance value has a direct effect on ripple current.Accepting larger values of ripple current allows the use of low inductances, but results in higher output voltage ripple and greater core losses. A reasonable starting point for setting ripple current is ∆I< 0.4 x I OUT (max). Please be no-ticed that the maximum ripple current occurs at the maxi-mum input voltage. The minimum inductance of the in-uctor is calculated by using the following equation:Inductor Value Calculationwhere (6)IN(MAX)IN V V = 1.2V · L · 340000)V -(V · V IN OUT IN OUT ≤(H)V · 408000)V -(V · V L INOUT IN OUT ≥Application Information (Cont.)Thermal ConsiderationLayout ConsiderationIn high power switching regulator, a correct layout is important to ensure proper operation of the regulator. In general, interconnecting impedance should be minimized by using short, wide printed circuit traces. Signal and power grounds are to be kept separating and finally combined using the ground plane construction or single point grounding. Figure 3 illustrates the layout, with bold lines indicating high current paths. Components along the bold lines should be placed close together. Below is a checklist for your layout:1. Begin the layout by placing the power components first.Orient the power circuitry to achieve a clean power flow path. If possible, make all the connections on one side of the PCB with wide, copper filled areas.2. In Figure 3, the loops with same color bold lines con-duct high slew rate current. These interconnecting im-pedances should be minimized by using wide and short printed circuit traces.3. Keep the sensitive small signal nodes (FB, COMP)away from switching nodes (LX or others) on the PCB and it should be placed near the IC as close as possible.Therefore, place the feedback divider and the feedback compensation network close to the IC to avoid switching noise. Connect the ground of feedback divider directly to the GND pin of the IC using a dedicated ground trace.The APW7302B maximum power dissipation depends on the thermal resistance and temperature difference between the die junction and ambient air. The power dis-sipation P D across the device is:P D = (T J - T A ) / θJAwhere (T J -T A ) is the temperature difference between the junction and ambient air. θJA is the thermal resistance between Junction and ambient air.For normal operation, do not exceed the maximum junc-tion temperature rating of T J = 125o C. The calculated power dissipation should less than:P D = (125-25)/50= 2(W)4. Place the decoupling ceramic capacitor C1 near the VIN as close as possible. Use a wide power ground plane to connect the C1, C2, and Schottky diode to provide a low impedance path between the components for large and high slew rate current.Figure 2.

These make it very easy to see the valve spool position during fault finding.A wide range of solenoid valvesA robust anodized aluminium valve housing, standard and low-temperature versions, hand lever with built-in catch for reliable retention in position, variants designed for a special NO (normally open) mobile solenoid valve, and several varieties of specialmobile (NC) solenoid valves make the valve an excellent choice in mobile applications.High reliabilityManual override - indication on the P2L-BA number of different versions of our solenoid valves P2E with 15 mm DIN 43650 form C enclosures are available to suit justabout any application. The valve has small installation dimensions,low energy consumption, large flow diameter, large flow capacity,a robust valve body, high reliability and long service life. With or without flush locking, extended non locking manual override, with long or short arm, spring biased or indexing.Low noise levelThe exhaust air from the pilot valves is exhausted through a silencer located in the end cover or body, to give the lowest possible noise level. This is particularly important for industries where low noise levels are required. The silencers make it possible for the valves to comply with the EU Machinery Directive,Noise 1.5.8.CertificationThe solenoid valves are protection class IP65 with the standard cable plug. The cable plug with reinforced protection raises the protection standard to IP67.Several types of cable plugsCompact installation dimensions - flexible installationValves easily comply with the requirements for componentreliability in accordance with the EU Machinery Directive standards EN292-2 and EN983.In the P2L-A: few moving parts combined with short spoolmovement give a valve with high reliability and long service life. It is designed for use with, or without supplementary lubrication.In the P2L-B and P2L-D: high molecular weight plastics with self-lubricating properties make it suitable for use with, or without supplementary lubrication.MaintenanceSize A and B spare parts = new valve.With or without suppression, LED and rectifier. For connection to your own cables or with molded cable. A large selection allows you to choose cables to meet your requirements.Insensitive to dirty airThanks to large flow passage areas and the large flow diameter of 1.0 in the pilot valves, the P2L-A, P2L-B and P2L-D can be used in normal industrial or mobile environments without any problems of sticking. However, the service life of the valve depends on thecleanliness of the air.

MK7-3型拦阻装置缓冲系统动力学分析
MK7-3型拦阻装置缓冲系统动力学分析MK7-3型拦阻装置是一种用于必要情况下快速制动飞机的航空器设备。
它可以被认为是一种机械缓冲系统，其原理类似于汽车的刹车。
在使用拦阻装置制动时，引擎的推力将被很快地减少，直到飞机全身被压在机载拦阻装置上。
这可以有效地防止飞机跑到跑道的另一端或撞上别的飞机或障碍物。
MK7-3型拦阻装置的缓冲系统包括的主要配件有过渡摆臂、滑车、缓冲桩和冲击装置。
其中，冲击装置可以是液压、气压或机械式的。
液压冲击装置是最常见的一种类型，因为它能够提供最优的动力学表现。
液压冲击装置可以提供多种不同的阻尼和缓冲力度，可以针对不同的需要进行调整。
MK7-3型拦阻装置的缓冲系统动力学分析主要涉及到四个方面的内容：动能、动量、速度和力。
动能是指飞机在着陆时的全部能量。
这个能量可以携带飞机几百吨的重量，因此需要被完全消耗掉。
动能的消耗是由拦阻装置的缓冲系统来完成的，主要靠挡板、阻力板和绷缩装置等来完成刹车过程。
这些部件需要经常维修和更换，以确保它们的性能始终如一。
动量是指飞机在垂直方向上的运动量。
它是通过拦阻装置的过渡摆臂来控制的。
过渡摆臂有两个作用：一方面，它可以将飞机从高速运动转换成减速和停止；另一方面，它可以控制飞机的下降速率，使飞机尽可能平缓地接触地面。
速度是指飞机在水平面上的运动速度。
在拦阻过程中，飞机的速度必须被迅速减少，因此大量的制动力度必须被施加。
这种制动力度是通过滑车和缓冲桩来完成的。
滑车具有很强的摩擦力，可以将飞机快速减速；而缓冲桩则可以在终止移动时吸收大量的能量。
力是指拦截装置对飞机的制动力。
制动力由引擎的减速、滑车的摩擦和缓冲桩的弹性组成。
这些力需要相互合作，以确保能够将飞机都制动和停止于跑道上。
总的来说，MK7-3型拦阻装置的缓冲系统动力学分析是一个复杂的过程，需要考虑到许多不同的因素。
这些因素包括飞机重量、飞机速度、拦截装置的阻力、摩擦力和弹性以及缓冲器的配置等。
