大连低地板有轨电车的动力学性能

Dynamic performance of Dalian low-floor tramcars

介绍国内第 1列低地板有轨电车的结构 ,比较了独立车轮与传统轮对的异同 ,对独立车轮转向架试运行情况进行了分析 ,通过试验证明其走行部具有较好的稳定性、平稳性和曲线通过等动力学性能 ,最后结合走行部的关键结构分析了该车的动力学特点及仿真结果。

The structure of the first generation of low floor tramcars in China is introduced with the comparison made on the similarities and differences between independent wheels and conventional wheelsets. Then analyzed is the trial running status of independent wheel bogie. It is proved that the running gear features excellent dynamic performances, such as stability, smoothness and curve negotiation etc. In the end analysis is made on the dynamic characteristics and simulation results of the tramcars combining the critical structure of the running gear.
