高速摆式客车转向架及其动力学特性

Dynamics behaviors of high speed tilting car bogie

铁路运输欲在竞争激烈的运输市场中占有一席之地 ,必须提高其运营速度 ,以缩短旅客和货物的运行时间 ,旅客列车提速已成为当今中国铁路的一项重大技术政策。采用摆式客车是在既有线路上提速的有效措施 ,摆式客车的关键技术之一是转向架。概述了国外几种主要摆式客车转向架的结构特点 ,介绍了中国铁道线路的基本情况 ,根据中国线路特点和摆式客车对转向架的特殊要求 ,提出了以一系柔性定位转向架作为中国高速摆式客车转向架的基本方案 ,并对其可行性和必要性进行了分析 。

If the raillway is just going to possess an eminent station in transportation market, it must improve its running speed to shorten the running time of passengers and freights. Today, the improving speed of passenger cars has become an important technology policy of Chinese railway. Adopting the tilting car is an effective measure to improve speed in the existing line. The bogie is one of the key technologies of the tilting car. The characteristic of several kinds of bogies of the tilting car abroad and the basic complexion of Chinese railways is introduced. According to the feature of track and the special demands of tilting car to the bogie, a project that the primary suspension of the bogie for the tilting car is soft, is put forward, and the feasibility and necessity are analyzed. The basic structure and dynamics of the bogie for Chinese tilting cars are discussed.2 tabs,3 figs,9 refs.
