摘　　要：为了突破列车动力学仿真的难题以及研究列车运行安全性,运用基于循环变量的模块化建模方法,对货物列车空重车混编条件下的曲线通过安全性进行了详细仿真分析。研究表明:车辆的曲线通过性能与列车惰行工况下较为接近,且明显好于列车牵引工况下的动力学性能;空车位于空重混编列车的不同位置以及同一列车中不同位置的空车,空车本身及列车的曲线通过安全性均有差异。期望借助新的方法和仿真结论,合理优化列车编组方式,以提高列车的曲线通过安全性。For the purpose of breaking through the problem of modeling of train dynamics and making research of running safety of train,a new modeling method named Modular Modeling Method Based on Circular-Variable was used to have a detailed analysis of the effect of mixed formation on the curving safety of freight train.It is indicate that the dynamics of vehicle is close to that of train in idling running condition,and both of them are better than the dynamics of train in traction state.Empty vehicles have different dynamics if they placed at the various locations.Both of the empty vehicle themself and the train would have various curving performances.In summary,we want to make a reasonable optimization of the formation of heavy haul train by dint of the new method and simulation results,and to improve the curving safety of train from the analysis.
