机械能力测试
机械能力测验机械能力测验是最早和最经常用于工业或军事测验中的特殊能力倾向测验。
有证据表明,存在着一种不明显的机械能力的一般因素,但大多数机械能力测验测量的能力很广泛,例如视—动协调因素、知觉及空间关系能力、机械推理和机械知识等。
组成分测验的各种机械能力彼此的相关都较低,但不同的机械能力分测验和总分之间具有较高的正相关。
在机械能力测验上存在性别差异,男性通常在空间和机械理解题上得高分,而女性在手部灵巧度与知觉辨别测验上较好,且这种差异与年龄成正比,这可能有文化因素的作用。
机械能力测验- 主要测验空间关系测验在20年代后期,帕特森(D. G. Paterson)及其同事在明尼苏达大学对机械能力作了严格的分析,结果产生了三个测验:明尼苏达机械拼合测验(Minnesota Mechanical Assembly Test)、明尼苏达空间关系测验?(Minnesota Spatial Relations Test)和明尼苏达书面形状测验(Minnesota Paper Formboard Test)。
第一个是工作样本测验,要求被试拼排随机排放的机械物体,测量动作敏捷性、空间知觉和机械理解,后两种测验为空间知觉测验。
在机械职业中已经发现,空间知觉是非常重要的因素,这种因素主要测量立体视觉及空间操作产生某种具体形状的能力。
1.明尼苏达空间关系测验由特拉布(M.R.Trabue)等修订,包括A、B、C、D四块板,两套几何形状的木块,一套插在A板和B 板的凹陷处,另一套插在C板和D板的凹陷处。
测验开始时,这些木块是零散摆放的,被试的任务是捡起木块并尽可能快地放入板中的特定凹陷处。
完成所有木块所需时间为10~20分钟,成绩按时间和错误次数记分。
测验信度高达0.80,测验与特定工作的相关在0.50左右。
2.明尼苏达书面形状测验由里克特(R. Likirt)和夸沙(W. H. Quasha)修订,为明尼苏达空间关系测验的纸笔形式。

The sturdy design includes various lubricant dispensing systems, speeds rang-ing from 0.001 RPM to 30,000 RPM, and temperature control. This allows the MFT-5000 to precisely develop, characterise, and quality control. Few of the common tribology tests and features are described below.The High Frequency Reciprocating module HFRR is used for evaluating diesel fuel lubricity. The ball slides against a disk with a 1mm stroke at a frequency of 50 Hz. ASTM D6079, D7688, CEC F-06-A-96, ISO 12156-1, IP450, BS-EC590HFRRThe standard test determines extreme pressure, friction wear properties of greases, solid bonded films, gear/hydraulic fluids, and lubricant oils. All tests are done in oscillation mode under controlled environmental conditions. ASTM G119, G174, G133, G203, G204, G206, D5706, D5707, D6425,D7217, D7420, D7594, D7421, DIN 51834 and more.Linear Oscillating/Fast Reciprocating Test, SRV TestThe block on ring module istypically used to evaluate friction, wear of materials or lubricant/grease where a ring/bearing/shaft is rotated under axialload. ASTM G77, D2509, D2714, D2782, D2981, D3704 and more.Block on Ring, Timken EP4 ball wear module is used to mea-sure wear-preventing properties of lubricants and greases in sliding and rolling applications; 4 Ball EP is to measure lubricant extreme pres-sure properties. The test involves rotating one ball on three station-ary balls at controlled environmen-tal conditions. ASTM D-2266,D-4172,D-5183D-2596, D-2783 and DIN 51350, IP 239,300.4 Ball Wear, 4 Ball EP, KRL Shear TestTapping Torque, Twist CompressionTapping torque module characterizes friction, wear, torque, etc., during form-ing and machining.

The multi-axis force measurement allows it to run several standard mechanical tests such as hardness, 3-4 point bending, tensile, compres-sion, fatigue, torsion, fretting, etc., tests with ease. All these tests can be done using any of the environmental chambers.Mechanical Tests - Hot Hardness, 3-4 Point BendingThe scratch test requires applying a load on the sample that needs to be tested with a spherical or custom tip. During the process of applying the load the sample is moved at a constant velocity and several parameters such as Friction (Fx), Down force (Fz), Coefficient of friction (COF), dis-placement (Z), acoustic emission (AE), temperature, etc., are measuredin-situ.Scratch Module Spherical Indents Vicker’s IndentWear Mark Hydrogels - Contact AreaChange vs ForceThe scratch test quantifies adhesion and scratch hardness of coatings. With the advent of new deposition methods and technologies, thinner coatings are finding their way in every aspect of our life. Coatings are present on LCD displays, phones, cutting tools, gems, glass, automobiles, medical devices, etc. The quantitative coating adhesion scratch test is a simple practical test that has been around for a long time. But reliable, reproducible, and comprehensive tests require precise control of the test system configuration and its testing parameters.Coatings Adhesion, Scratch, and Mar ResistanceScratch nm to mmThick CoatingsHigh Temperature• Hard Coatings• Polymer Coatings• Paints• Soft Coatings• Optical Lenses• Decorative Coatings• Real Components• 2D Materials•Thermal Spray CoatingsCoatings and MaterialsFrettingUnmatched PerformancePrecision At BestThe tribometer uses decoupled capacitive load cells to measure friction at a COF 0.001 level even at high down forces (1N, 10N etc.). The unique design, controlled en-vironmental condition, and high resolution sensors measure friction for 2D materials, and superlubricity with ease.SuperlubricityIn-situ Confocal Raman SpectroscopyTouch Screen, Display, and GlassContact Area vs ForceIn-line confocal Raman spectrosco-py can be added to the tribometer. The confocal mode allows to image the chemical property of locations within the wear mark with high resolutions. The XY stage allows stitching of the Raman maps across the entire wear track. The test can be performed in air, inert gas, or in a vacuum chamber.The tribometer uses a 6D sensor and closed-loop XY stage to cre-ate customized motions, such as butterfly, circular, and zig-zag that simulate any kind of profile. The test is used to simulate finger mo-tion on touch screens accurately to quantify perception.The surface adhesion module can be added to the tribometer to ana-lyze real time contact area vs force using and imaging system that is placed under the sample. This cal-culates surface adhesion and alsoobserves the interface in real time.Ball on disk setup for nano tribology agglomerated particles on a coating.Vacuum chamber with in-line Raman and profiler Raman spectrometer data on a wear mark.A test showing hydrogel against a coated glass slide. Real time contact area analysis vs force.Nano Tribology• 2D Materials • Polymers • Soft Coatings • Paints • Lens• Optical Coatings • DisplaysThe nano tribometer modules allows for a comprehensive friction, wear, adhesion, etc. characterization over nano to micro scale. Ultra sensitive capacitive load cells, combined with low floor noise, and a robust design provide quantita-tive tribology characterization of interfaces, thin films, 2D materials, superlubricity, and much more. The tests can be done in air, vacuum chamber, or in a controlled inert gas atmosphere. The wear mark can be easily imaged using in-line profilometer and Raman spectrometer to characterise roughness, wear and chemical property across the track au-tomatically.Ultra Low Friction,nm to Micron Films, CoatingsSoftwareThe tester comes with a powerful operation, statistical and image analysis software. All software is Win-dows based and is very easy to learn and operate. The software runs the tool in advanced mode for ex-perienced users, or simple mode for new users or operators.

5.Tensile Testing(拉伸试验)
Tensile Testing(拉伸试验)Tensile testing is one of the most widely used mechanical tests.A tensile test helps determining tensile properties such as tensile strength, yield point or yield strength, % elongation, % reduction in area and modulus of elasticity.Since mechanical properties are to some extent influenced by the size and shape of the test specimen, it is customary to use standardized specimen.The essential feature of a round (cylindrical) test specimen are the diameter D. parallel length PL, gauge length L., and end fillet radius r. These dimensions may be set as follows:Diameter 10mm D0Parallel length 55mm 5.5 D0Gauge length 50mm 5 D0End fillet radius 3mm rTensile test is carried out by gripping the ends E, E of the specimen in a tensile testing machine and applying and increasing pull Fig. On to the specimen till it fractures.During the test, the tensile load as well as the elongation of a previously marked gauge length in the specimen is measured with the help of load dial of the machine and extensometer repectively.These readings help plotting stress-strain curve as shown in Fig.After fracture, the two pieces of the broken specimen are placed as if fixed tighter and the distance L between two gauge marks and the diameter D at the place of fracture are measured.The various tensile properties are calculated as follows:1. Yield strength=Load at Yield point/A0i.e.(Π/4).D022. Ultimate tensile strength=Ultimate load, P max/A03. % Elongation=[(L1-L0)/L0]×1004. % Reduction in area=[(A0-A1)/ A0] ×1005.
