乘用车列车驾驶安全性逐渐受到业界关注。基于CarSim动力学仿真软件，依据GB/T29121试验方法对乘用车列车进行了横向稳定性仿真分析，验证了挂车主要参数的变化对横向稳定性的影响，明确了提高横向稳定性的手段有降低车速、减小挂车质量惯量、质心位置前移、增大轮胎侧偏刚度等，可得出，CarSim模型对横向稳定性研究更有实际意义。

Passenger trailer combination driving safety has gradually attracted the attention of the industry. Based on the CarSim dynamic simulation software and GB/T29121test method, the lateral stability simulation analysis of passenger trailer combination was carried out. Verified the influence of the changes of the main parameters of the trailer on the lateral stability. Identified the means to improve the lateral stability, such as reducing the speed,reducing the mass inertia of the trailer, moving forward the position of the center of mass, increasing the side stiffness of the tire, etc. CarSim model is more practical for the study of lateral stability.
