摘　　要：为了解决重载列车动力学仿真过程中遇到的自由度繁多的问题,本文利用一种在三维空间将列车系统耦合起来的建模及求解方法——基于循环变量的模块化方法对重载列车曲线通过安全性能进行研究。分析表明:位于曲线线路不同区段转折点上的车辆,其动力学性能差于其他位置的车辆,列车曲线通过性能与曲线线路位置密切相关;曲线半径及缓和曲线长度等因素对重载列车动力学性能有重要影响。In order to solve the difficult problems of numerous degrees of freedom in simulation of train dynamics, a new modular modeling method based on circular-variables was developed for coupling of the train system in the longitudinal, lateral and vertical spaces. The curve negotiation performance of heavy-haul trains were studied with this method. The analysis shows as follows： The vehicle at the transition point of line sections demonstrates worse dynamic performance than vehicles at other points, the curve negotiation performance of a train is closely related with the position of the train on the curve; the curve parameters such as the curve radius, the length of the transition curve and so on, have an important effect on the dynamic performance of a heavy-haul train.
