摘　　要：针对汽车操纵稳定性实车试验危险性大,对试验驾驶员素质要求高的问题,在对ADAMS(automatic dynamic analysis of mechanical systems)二次开发模块ADAMS/CAR研究的基础上,建立了基于某轿车车型的ADAMS整车模型和驾驶员控制模型。按照国家标准GB/T6223.5-1994对汽车转向轻便性试验进行了设计,在ADAMS虚拟仿真平台下进行了虚拟试验,并对试验结果进行了计算分析。结果表明,驾驶员模型对整车模型有较强的操控性,虚拟试验结果满足评价指标,可利用设计虚拟实验来达到对车辆性能进行测试和改进的目的。In an effort to address the high risks and qualification demands of test drivers, a vehicle model and a driver model were built based on ADAMS/CAR, an advanced block of ADAMS. The steering efforts test procedure was designed according to the national standard GB/T 6223. 5--1994. A virtual test was performed in ADAMS, and the results calculated. The results show that the driver model possesses a strong capacity to charge the vehicle model. The virtual test results satisfy the evaluation index, indicating the virtual test can he used to test and improve vehicle performance.
