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 built 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 was 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.
