摘要

现有计算方法对于长编组浮车型有轨电车的重量计算较为繁琐，为研究重量分配计算新方法，以7模块100%低地板有轨电车为研究对象，基于浮车型有轨电车相邻车辆间的铰接结构形式，以超静定理论为基础，将有轨电车车体及其安装设备简化为刚体，采用虚位移原理推导刚体系的静力学平衡方程，通过变形协调原理分析不同车体的受力状态，计算车辆轴重和轮重。编写计算机程序将方法参数化，将计算结果与有限元法进行对比分析。结果表明文中计算方法合理有效，可应用于100%低地板有轨电车设计过程的重量管理。

Abstract

The existing calculation method is cumbersome for the weight calculation of long-term group of suspended-modular tram. In order to study the new method of weight distribution calculation, the 7-module 100% low floor trams were taken as the research object. Based on the articulated structure between adjacent vehicles of floating type trams and the statically indeterminate theory, the tram body and its installation equipment were simplified as rigid bodies, and by adopting the virtual displacement principle, the static balance equation of the rigid system was derived, and the stress state of different vehicle bodies was analyzed with the deformation coordination principle, and the axle load and wheel weight of the vehicle are calculated. A computer program was written to parameterize the method, and the calculation results were compared with the finite element method. The results showed that the calculation method was reasonable and effective, and could be applied to the weight management of 100% low floor tram design process.
