Abstract: The development of automotive industry brings the vehicle consumers with higher requests for good power performance and fuel economy, as well as excellent handling stability and safety. Steering returnability is an important evaluation index of the vehicle steering stability. In this paper, we use the ADAMS software to build up vehicle multi-body dynamics model, and carry out the dynamic simulation analysis of the vehicle steering returnability performance according to the test method for vehicle handling stability. Based on the analysis results, we carry out the optimization design to improve the vehicle steering return-positive performance and shorten the project development cycle effectively.
