Modeling and Simulation of 1/4 Vehicle Suspension Based on Simulink
Zheng Lihui Zhang Yuezhong
Abstract：The article takes 1/4 vehicle suspension as the research object， and establishes dynamic differential equations based on suspension dynamics theory. In Matlab/Simulink environment， a road excitation model and a 1/4 suspension system dynamics simulation model are built to simulate the three evaluation indexes of body acceleration， suspension dynamic stroke， and wheel dynamic load to measure the comfort of suspension， so as to provide technical reference for suspension design.
