Abstract
Air spring is characteristic of variable stiffness, its natural vibration frequency is much lower than that of leaf spring and will not change with load of vehicle. The vehicles mounted with air suspensions possess lower dynamic load of the wheels. It provides better ride comfort, better controllability and stability and safety. And it can minimize damage to road when the vehicle is at a high speed. More and more air suspensions are applied in automobile suspension. A study on air suspension bus ride comfort simulation is presented in the paper, which is based on multi-body system dynamics.
