Study on Comprehensive Performance Testing Table and Intelligent Measuring Technology of Constant Velocity Universal Joint Assembly

Abstract

A comprehensive performance testing table, on which 9 testing items can be done, of the constant velocity joint drive shaft assembly is developed. The principle of the system is introduced and the mechanical structure and the computer measuring and control system of it are discussed particularly. Some intelligent measuring methods, such as fuzzy method, are used in the system and an example of testing the slip curve characteristic of the joint assembly by fuzzy measuring method is presented in detail, including its membership function and fuzzy rules of fuzzy reasoning. The slip curve measured by traditional method compared with that by fuzzy method. The experimental results show that the measurement precision by fuzzy method is more accurate than that by the traditional one.
