Analysis of Kinetic Characteristic and Structural Parameter Optimization of Multi-Link Suspension

Taking the five-link suspension of a car as the subject investigated on the basis of ADAMS/Car, this paper builds the parameterized mode of the multi-link suspension. The simulation shows the influence relations among multi-link suspension structure parameter and the wheel location parameter, wheel track, roll center. On the base of this, aim for improving the ride safety and comfort, multi-link suspension optimization model is built and carried out parameter optimization design by using ADAMS/Insight. The result shows that this method is high-performance and can be used in the design of multi-link suspension conveniently.
