| 摘 要： | 建立包含可变鞍座阻尼力矩的汽车列车数学模型,采用轻微制动与施加转向轮横向扰动来模拟汽车列车的惰行工况。仿真分析了该工况下系统横摆加速度和横摆角速度等运动参数的变化响应,并初步探讨了施加鞍座阻尼力矩对横向稳定性的改善作用。研究结果表明:横向扰动是产生系统摆振的主要因素,施加适当的鞍座阻尼力矩可有效改善系统横向稳定性。

| Abstract: | A tractor-trailer mathematical model including the alterable saddle damping moment was established.The idle running condition of tractor-trailer using slight brake and imposing transverse perturbation of steering wheel was simulated.The change response to motion parameters of the system such as yaw acceleration and yaw rate were simulated and analyzed under the idle running condition.The improvement for lateral stability in the role under the saddle damping moment was discussed.The results show that the tra... |
