摘要
因试验设备结构、功能不同,导致车用摩擦材料摩擦磨损性能的小样试验结果与台架试验相差较大。为提高小样试验与台架试验的可比性,依据相似原理,并参照现有JF122型轻轿车1∶1惯性台架试验机的参数,研制了JF122SB型摩擦材料1∶5缩比台架摩擦试验机,用于轿车盘式制动器摩擦衬片的缩比试验。介绍了1∶5缩比台架摩擦试验机的设计准则、缩比比例、主要参数和结构,并采用同一个试验方法标准SAEJ2681,与1∶1台架进行了对比试验,结果表明二者的试验数据具有良好的一致性和可比性。
There is more difference in the test data of the friction and wear for friction material between the small sample tester and dynamometer,because of the different structure and function. In order to improve the comparability, a kind of new scaling 1：5 for JF122SB dynamometer for the scaling testing based on the parameters of the scaling 1：1 for JF122 dynamometer was developed according to the similarity principle. The designing principle, zoom scale, main parameters and structure of 1：5 dynamometer were introduced. Adopting the same testing standard SAEJ2681, the comparative trial was done with JF122 dynamometer. The result by analyzing the test data shows that there are fine comparability and consistency between the two testers.
