In this paper, the multi-body system dynamics theory, mechanical system simulation software ADAMS / Car Tools to establish Hunan University FSAE racing vehicle virtual prototype , and dynamic simulation and evaluation of vehicle handling and stability , while the axle load distribution , centroid height , steering system drive ratio, tire cornering stiffness and tire width variable , to analyze the influence of racing handling and stability , and to suggest improvements . First introduced to study the contents of the vehicle handling and stability evaluation system with multi-body system dynamics theory , analysis mechanism ADAMS calculation discussed . Then FSAE racing vehicle in accordance with the basic flow of the vehicle virtual prototype modeling , virtual prototyping . Using different control methods , according to the requirements for the handling and stability test , the preparation of the corresponding control file , define the control parameters , simulation test status , national standards according to the actual test run of the virtual prototype vehicle . Closed-loop test for the driver - vehicle - road system , the way to provide closed-loop control method using ADAMS , mimicking the operation of the driver feedback according to the condition of the vehicles and taken . The focus of this paper is to analyze the influence of the five factors on each of the handling and stability test , the final comprehensive evaluation of handling and stability , and suggest improvements based on FSAE racing . The entire research work to the virtual design of automotive products , virtual analysis as the core , the initial realization FSAE racing vehicle dynamics computer simulation of the handling and stability analysis FSAE racing manipulation stable performance and the influencing factors and laws for FSAE racing improvements and design of practical significance .
