摘　　要：为了进一步研究半挂汽车列车弯道行驶横向稳定性,运用动力学理论以及虚拟样机仿真软件ADAMS,建立了具有21自由度的半挂汽车列车虚拟样机,通过将稳态转向试验和转向盘角阶跃输入试验所得仿真结果与实车试验所得曲线相比较进行仿真模型的校验,分析了半挂汽车列车在弯道行驶极限工况下有关参数与时间的变化关系曲线,并分析极限工况所产生的原因。In order to further study the lateral stability of semi-trailer train running along a curve, the virtual prototype of semi-trailer train which has 21 degrees of freedom was fabricated with the theory of dynamics and the virtual prototype software ADAMS. The simulation results from steady-state steering tests and steering wheel angle step input tests were compared with the curves from the real vehicle tests for simulation model verification. The relations of the relative parameters with time of the semi-trailer train running along a curve under the ultimate condition were analyzed. At the same time the reason of the ultimate case was also researched.
