| 摘 要： | 分析了半挂汽车列车转向的特点,对其稳定性控制原理进行了研究,包括横摆角速度跟踪控制和防倾覆控制.在此基础上,建立了半挂汽车列车多体动力学模型,采用虚拟样机技术,对横摆角速度跟踪控制和防倾覆控制进行运动学与动力学仿真.结果表明,装用车辆动态控制系统后,提高了半挂汽车列车高速紧急避障时的操纵稳定性,因而,其避障行驶的极限条件大大宽松.

| Abstract: | The feature of steering for semi-trailer combination is analyzed,and the principle of stability control,including yaw rate tracking control and anti-roll control,is studied.Based on this,a multi-body dynamics model for semi-trailer combination is set up,and the kinematics and dynamics simulations for yaw rate tracking and anti-roll controls are performed using virtual prototype technology.The results show that with vehicle dynamics control,the handling and stability of semi-trailer combination in high-speed... |
