摘　　要：针对列车行驶的安全性、舒适性及可靠性问题,基于某地铁的动力学参数进行建模,运用SIMPACK动力学软件完成模型的建立与分析。结合列车实际运营时遇到的线路不平顺、重载、曲线半径过小等问题,分析其动力学性能。试验中根据脱轨系数、轮重减载率、轮轴横向力等指标参数,对列车运行的平稳性及稳定性进行评估。With regard to the safety, comfort and reliability of trains in operation, the dynamic parameters of a certain subway are applied to build and analyze the model by SIMPACK dynamics software. The dynamic performance of the train in actual operation with the problems like uneven line, heavy load, over small curve radius, etc. is analyzed. And the smoothness and stability of the train operation are evaluated based on the index parameters such as derailment coefficient, wheel load reduction rate, and axle lateral force.
