本文通过理论计算确定209型及202型客车转向架轮对的纵向和横向定位刚度,使其蛇行运动的临界速度远超出常用速度范围,以保证稳定运行。探讨悬挂参数对横向振动性能的影响。论述轮对蛇行运动的特性及其与车体横向振动之间的关系。并证实了车体滾摆振动是由轮对蛇行运动所激起的。
In this paper, the longitudinal and transverse positioning stiffness of 209 and 202 passenger car bogie wheelsets are determined theoretically to make the critical speed of the meandering speed far beyond the usual speed range to ensure stable operation. The influence of suspension parameters on lateral vibration performance is discussed. Discusses the characteristics of the wheel pair snake and its relationship with the lateral vibration of the body. And confirmed that the body rolling vibration is caused by the wheel on the snake movement.
