基于鞍座因素的半挂汽车列车横向稳定性研究

针对轿车操纵稳定性研究方法在汽车列车研究中的局限性,探讨了一种适合于研究汽车列车操纵稳定性的方法和改善措施.根据所建包含鞍座阻尼的半挂汽车列车系统动力学模型,进行了"S"移线工况下汽车列车运行状态的计算机仿真与分析,揭示了挂车相对牵引车侧倾角、横向加速度等运动参数的变化响应,并通过施加鞍座阻尼力矩来改善系统的横向稳定性.研究结果表明阻尼力矩能有效减小系统的横摆振幅和摆振频率,为研究半挂汽车列车操纵稳定性提供了参考和借鉴.

Research on the Lateral Stability of Tractor-semitrailer Based on Saddle Factor

Considering the limitations when the handling stability research methods of cars are applied to tractor trailer,a new research method and an improved measure for handling the stability of tractor-semitrailer were proposed.A system dynamic model of tractor-semitrailer including saddle damping parameter was established,and computer simulation was done under 'S' lane-change working conditions.The relative change response characteristics of the tractor's motion parameters,such as the rolling angle and lateral a...
