摘要
轨道车辆的二系悬挂直接将车体和构架连接在一起,主要用于车体相对于转向架的缓冲减振,其性能好坏直接影响到车辆的乘坐舒适性和曲线通过性能。文章根据车辆运行的线路条件,基于车辆的悬挂系统所需满足的运动变形边界条件,对几种多点支承二系悬挂方案进行对比分析,以选出最优方案。
The secondary suspension system of railway vehicles connects the car body and the bogie frame,and it is mainly used in shock absorption between car body and the bogie.Its performance will affect the ride comfort and curve passing performance directly.Based on the lines condition and relative move condition that the system has to satisfy,some kinds of structure of multi point support secondary suspension system will be discussed and compared in this article to find a better system.
