Suppressing Actuator Simulation Analysis Based on Matlab

Abstract

In order to analyze the dynamic response of the suppressing actuator, the dynamic simulation model of the suppressing actuator based on MATLAB is established in this paper. According to the principle of the suppressing actuator, the suppressing actuator model is presented based on mass-spring-damper system. To simulate the collision between brake lining and brake disc, a Herbert-Mcwhannell collision contact model is introduced to perfect the dynamic model of the suppressing actuator. And the dynamic model simulated in Matlab/Simulink. Then the influence of the fluid pressure P and the restitution coefficient Cr is analyzed. The results show that the optimized hydraulic pressure control can reduce the actuating overshoot, and the brake lining of low restitution coefficient can shorten the response time of the actuator.
