摘要
通过建立使用槽型轨和无槽轨轨道的70%低地板有轨电车动力学模型,分析了发生轮背接触的条件,研究轮背接触对槽型轨的动力学影响,优化滚动圆横向跨距。计算结果表明,轮背接触对轮对十分不利,在设计车辆时应保证轮对与槽轨尽量不发生接触;增大滚动圆横向跨距是避免轮背接触的有效方法,且适当地增大滚动圆横向跨距对车辆动力学性能有益。
The dynamic models of 70% low-floor trams using groove track and non-groove track were established respectively.Several aspects were discussed including analysis of the condition which occurs flange contact,exploring flange contact effects on dynamic of groove track,optimizing the distance of rolling tread circle.The results of the dynamic performance of trams based on groove rail showed that:flange contact is very unfavorable to wheel alignment,so it is necessary to ensure that the wheel is not in contact with the groove track in vehicle design;increasing the distance of rolling tread circle is a quick way to avoid the flange contact and proper increasing the distance of rolling tread circle is beneficial to vehicle dynamic property.
