摆式列车动力车转向架方案比较分析

Dynamic Analysis for Bogies of Locomotive Driving Tilting Train

对比分析了二轴与三轴转向架、自导向径向与非径向转向架的曲线通过性能 ,为摆式列车动力车转向架方案比选提供依据。分析表明 ,二轴传统转向架和三轴自导向径向转向架均能满足列车曲线提速的要求。从结构复杂性和技术成熟度看 ,摆式列车的动力车可优先考虑采用二轴传统转向架 ;其次为减轻轴重 。

Curve negotiating performance of driving bogies with two or three axles, and with traditional or self steering wheel sets are analyzed in this article in order to prove the bogie concepts for the first prototype tilting train in China. It shows that two axis bogie without steering wheel sets or three axis bogie with steering mechanism both meet the increased curve negotiation speed requirements for tilting trains.
