Abstract In order to establish the virtual prototyping model of a certain FSAE racing car and to assess its handling stability, the model of a certain Formula SAE racing car was established by applying the ADAMS/CAR module of mechanical system simulation software ADAMS. The main points and process of the modeling were introduced. The model of the race track was built and the best path of racing car in the track was obtained by ADAMS/CHASSIS. The extreme driving performance of the racing car in the track was calculated through Smart driver module simulation. By comparison to the actual results of competition, the correctness of the virtual prototyping model is verified, which provides a strong basis for the design and optimization of Formula SAE racing car. Based on the above results, the handling stability test of virtual prototype was performed. 〖JP2〗The research results show that the understeer tendency of the racing car is obvious, which achieves the design goal.

基于ADAMS的FSAE赛车建模与操纵稳定性仿真
为建立某FSAE赛车的虚拟样机模型及评价其操纵稳定性，采用机械系统动力学分析软件ADAMS中的ADAMS/CAR模块,建立了某中国大学生方程式(FSAE)赛车模型,并介绍了建模的过程及要点.建立了比赛赛道的模型,利用ADAMS/CHASSIS得到赛车在此赛道上的最佳行驶路径.利用Smart driver模块仿真得到赛车模型在此赛道的极限行驶性能.通过与比赛实际成绩的比较,验证了虚拟样机模型的准确性,为方程式赛车的设计及优化提供了有力依据.在此基础上进行了操纵稳定性的仿真试验,结果表明,赛车具有明显的不足转向趋势，符合设计要求．
