Multi-body Dynamics Simulation Technique Applied to Off-road Vehicle Design Stage

A off-road handling simulation model was built by using multibody dynamics sof tware ADAMS. In the model,we have considered the f ront and rear suspension system,steering system and the tires model in detail,also the connect bushing effect was included in this study.Compare the simulation reaults with the road test reaults,it got a reasonable dynamics mode.So we analysis the vehicle handling and stability,and provide the design methods.
