Matching Design of Automobile Air Suspension System Based on Ride Comfort

Yang Qi-yao

Abstract

A ride comfort model of automobile was established based on air suspension system,MATLAB optimizing toolbox and characteristics of air spring were used to matching design the stiffness and damping of air suspension system in 7 workingconditions,then computer simulations were carried out and the results were validated under the MATLAB/Simulink environment.The simulation results showed that the optimized air suspension could effectively reduce the vibrations caused by road inputs and apparently improve ride comfort.
