车辆限界计算方法对比研究

Comparative Study on Computation Methods for Dynamic Car Profiles

论述车辆动态限界计算不仅是车辆设计过程中一项重要内容,也是安全行车的重要保障。认为随着动态限界计算理论的日趋成熟,车辆动态限界计算理论和方法也多种多样。为了更加清晰地了解各个方法之间的差异,以某车辆参数为参考,分别用不同的计算方法进行计算,找出各个计算方法之间的不足,为同类问题计算提供参考。

Computation of dynamic car profiles is an important content in the process of vehicle design and also the guarantee for safety operation. With the development of the dynamic theory, different methods have been invented. In order to understand the differences among these methods, authors made a comparison between these methods in terms of the parameters of a metro carriage by using different calculation approaches. Disadvantages of these computation methods are identified for reference by similar studies.
