Minibus Kinematics / Dynamics Simulation

Based on the theory of Multi_body Dynamics , this thesis use ADAMS_View to establish the multiple free limit model of a certain kind of subminiature vehicle and evaluate the vehicle ride through studying the vehicle multiple geostatics, moreover, it study the major affect factor of vehicle ride and research the methods of using ADAMS to evaluate the vehicle ride. It also use ADAMS_Car to build the kinematics model of front suspension, studying the varying rule of front wheel orientation parameter.In the process of building model, the method of using experiments to collaborate with computer to acquire parameters was used. The front wheel orientation parameter, the absorber damp speciality and the quality of parts were all acquired by actual measure. The spring rigidity etc are acquired by calculation. By this way the model can approach the practical instance.Through comparing the road experiments with the result of simulation the corresponding vehicle kinematics model that was bulit by ADAMS was confirmed to be reliable; This article adequately utilize the trait of ADAMS to do a lot of suspension kinematics simulation calculation and deal with the sensitivity degree to acquire the affect rule of these parameters. It use ADAMS to simulate the front suspension kinematics and gain the rule of suspension frame affecting the front wheel orientation parameter.
