Optimization and comparison of passive, active, and semi-active vehicle suspension systems

摘要

In the vehicle suspension design the optimal suspension should fulfil the following basic requirements: the ride comfort, reduction of dynamic road-tyre forces, and reduction of relative motions between the vehicle bodies. Controllable suspension systems are required to improve the compromise between the conflicting demands. In the paper the performances of the passive suspensions are optimized and compared with the performances of active and semi-active suspensions (quarter car models).
