UMT Tribolab 试验机 CT 模块湿式摩擦副界面温度测试方法

The wet friction pair is the core component of the mechanical transmission system. Thermal damage is the main failure mode. The measurement of the instantaneous temperature of the friction pair contact surface is the key to research this kind of problem. The real-time temperature measurement system of wet friction pair test based on UMT(Universal Mechanical Tester) friction and wear comprehensive testing machine is designed by arranging temperature sensors at different depths in the radial direction of the friction plates, and a temperature test method and a detailed experimental plan are proposed, which is aimed at the current situation that the real-time temperature of rotating contact surface is difficult to measure. Experimental data shows that the test system can realize the real-time measurement and acquisition of the temperature at different positions of the friction interface in the friction-sliding process, which provides a reliable test method and data for the wet friction pair thermal analysis.
