Integrated Performance Optimization of Suspension Parameters Based on ADAMS

Based on the theory of mutibody dynamics,a virtual prototype model of a truck is built by using ADAMS,to study the impact of suspension system on comfort for the crew and the destructive action of vehicles on the road.Numerical calculation is carried out in terms of the Appraisal criterion of the ride comfort and road friendliness,the influences of road grade,traveling speed,suspension spring stiffness and shock absorber damping upon vehicle ride comfort and road friendliness are analyzed,getting optimized suspension parameters in the end.With a comparison of dynamic tire forces before and after optimization,some helpful conclusions about suspension design and application are made.
