Analysis of swinging angle hydraulic detection system of constant velocity universal joints based on MATLAB

The life-cycle test-bed of automotive constant velocity universal joints is the major equipment that can realize assembly of automotive constant velocity universal joints, the relevant performance test of constant velocity universal joints and other components like automotive semiaxle and so on. This paper analyzed the problems of hysteresis quality and stuck caused by rapid reversal brake exist in the original swinging angular hydraulic detection system, and revised the design of swinging angular hydraulic detection system based on the technology of electro-hydraulic proportional control. Established the mathematical model of hydraulic system based on MATLAB/Simulink, simulated the dynamic properties of the system, then proved that the dynamic characteristics of the hydraulic system based on the electro-hydraulic proportional control technology has improved insignificantly.
