摘要: 对该机原主离合器的结构及其工作性能对测试精度的影响进行了分析,提出了对主离合器的改进设计,并设计了可控自动加力装置代替原测静摩擦系数时人工扳转主轴。改进后的试验机与美国SAENo.2离合器摩擦试验机性能相近。还探讨了打滑线速度对静摩擦系数的影响。Abstract: The paper has analysed the influence of the structure of original main clutch in tester and its performance on testing accuracy, put forward an improvement design for main clutch and designed a controllable automatic device for force increment substituting for mannual converting main shaft, originally used for testing static friction factors. The properties of the tester improved approach to those of SAE No. 2 friction tester for clutch. Furthermore, the influence of slip linear speed on static friction factor has been discussed.
