胶轮导轨电车整车结构形式研究
|
摘要
在现有胶轮导轨电车的整车结构形式的基础上,提出一种新型M+T+M的3模块编组形式,并对空气弹簧数量对车体与走行部位置变化影响、减振器影响、轴桥铰接方式进行研究。计算结果表明:2个空气弹簧的支撑模式在出曲线时的波动幅值及收敛时间上高于4个空气弹簧的支撑模式;通过在车体与走行部之间添加减振器能够较好地降低2个空气弹簧支撑模式下的波动幅值和收敛时间;在使用4个空气弹簧时两轴桥通过转动铰连接表现出较好性能,当使用2个空气弹簧时使用固定铰连接性能更佳。
On the basis of the entire vehicle structure of the existing rubber tire train,a new type M+T+M three-module marshalling form was proposed.The influence of the number of air springs on the changes in the position of the vehicle body and the running gear,the influence of the shock absorber,and the articulation method of the axle bridge were studied.The calculation results showed that the support mode of the two air springs was higher than the support mode of the four air springs in the amplitude and convergence time of the outgoing curve.By adding shock absorbers between the vehicle body and the running section,the amplitude and convergence time of the two air spring support modes could be well reduced.When using four air springs,the two-axle bridge showed better performance through a swivel joint,and the use of fixed hinges provided better performance when two air springs were used.
