Abstract


At present, our country as a car manufacturing power failed to become a power because of the lack of t core technology of developing automotive product. At the same time, China’s automotive dynamics technology is still in direct purchase products, introduced or imitation stage. Set up electric auto simulation model using virtual prototype software ADAMS/Car in this paper. Do handing and ride performance optimization design using ADAMS/Insight module.to the car steering stability of the peace of collaborative optimization design. For vehicle dynamics research provides an effective analysis and optimization method. The main research contents and innovation are as follows:(1) Determine a project of chassis layout, and check the strength of vehicle frame and axles based on EV dynamics theory research.(2) Apply ADAMS/Car software to build Macpherson front suspension, steel leaf spring, diving electric generator, power battery system, steering system, front and back tires and body subsystem model, etc. Assemble subsystems in accordance with the actual situation of the physical sample to complete EV simulation model.(3) Write a driver control documents and drive parameter to do4kinds of stability tests with the virtual prototype model according to the requirements of the national standard. Analysis and evaluate the handing performance of EV.(4) Establish a grade B road files to do random road input and pulse road input ride comfort tests with the virtual prototype model, and analysis and evaluation the ride performance of EV.(5) Apply ADAMS/Insight to optimize Macpherson front suspension and the whole vehicle’s handing and ride performance with experimental design and analysis optimization method.(6) Do the road test for the design and development of EV, to verify the accuracy of the model and the feasibility of optimization design by compared with the experimental results and simulation results.
