摘　　要：铰接处的受力状态是决定铰接式低地板城轨车辆运行品质和设计合理性的重要指标之一。为了使铰接处的受力能够合理分配,首先,以某三节编组复铰式低地板车辆为研究对象,基于模块分离有限元计算方法,建立了典型工况的平衡方程,通过数值计算得到各个铰接位置的铰接力大小;然后,基于MATLAB程序,研究了低地板车辆设计参数变化对各个接口处铰接力的影响,得到了接口力随设计参数变化的规律。研究结果表明:车体重心位置对铰接力的大小有重要影响,在不同工况下,重心位置对不同铰的影响趋势不同,但是都是关于质心位置的单调函数。The force situation of articulated element is the key factor that determines the service quality and reasonability of design for the articulated low floor train. In order to distribute the forces on articulated parts properly, this article, based on an articulated 100% low floor train with three cars, built the balance equations of the given load cases with module separation method, and calculated the force value of articulation parts. Furthermore, with the help of MATLAB, it discussed what influence would it have when certain car-body parameters changed on jaint forces. As it shows in the results, for the articulated train, the location of vehicle centroid has a significant influence on jaint forces. The influence to the same joint force under different lode cases varies. However, some rules do exist, which will be given in this paper. The rules given in this this article and the research method this paper used are of important meanings for the design of vehicle centroid distribution.
