| 摘 要： | 为了解决地铁车辆踏面过度磨耗、剥离、失圆及产生的车体垂向动力学性能超标问题,通过车辆结构理论分析及动力学仿真,研究了牵引杆的附加刚度效应.结果表明:车辆制动系统不是导致上述问题发生的主要原因,短牵引杆及其两端大的连接刚度引起的附加刚度效应是导致车体对垂向振动冲击敏感的根源；在车辆制动或通过曲线轨道时,牵引杆装置的附加刚度效应可降低二系悬挂系统的隔振能力；考虑牵引杆的附加刚度效应时,车辆对垂向振动的冲击响应显著增大；将牵引杆的连接刚度减小到现有刚度的25％时,可以降低车体对垂向冲击的响应,改善车辆的垂向动力学性能. |

| Abstract: | To solve the wheel wear problems of the subway vehicles such as wheel tread wear,spalling,wheel out of round,and the problem that the vertical vibration of car body and the vertical ride index exceed the standard values,the additional stiffness function of the traction bar was studied through theoretical structure analysis and dynamic simulation.The results show that the vehicle braking system was not the main cause of the above problems,and that the additional stiffness function caused by the short length ... |
