The Development of the Scaling 1:5 Friction Material Dynamometer Based on the Similarity Principle

Abstract:

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. In this paper, it is show that the designing principle, the zoom scale, the main parameter and structure of the 1:5 dynamometer. Adopting the same testing standard SAEJ2681, the comparative trial has been done. Analyzing those test data it is proved that there are fine comparability and consistency between the two testers.
