摘要
根据列车纵向动力学原理,利用VC编制列车纵向动力学仿真计算软件。利用仿真计算软件,对重载组合列车在平直道上牵引工况下的纵向动力学性能仿真计算和分析,以帮助确定合理的列车编组和试验方案提供理论依据。针对重载组合列车3种不同编组情况下的纵向性能,研究在平直道上牵引工况下纵向动力学性能,从而得出比较合理的编组,并且通过计算不同提手柄时间的最大车钩拉压力、最大正负加速度以及列车纵向冲动,分析不同提手柄时间对列车纵向性能的影响。
In order to provide theoretical basis for train formation plan and experimental scheme,longitudinal dynamics simulation and analysis for train running on straight line with traction are carried out by the train longitudinal dynamic software which is made with computer language VC according to concerning principle.More reasonable train formulation plan is got by studying train longitudinal dynamics with traction according to longitudinal forces in three different train formulation plans;and the influence of different extracting handle moment on train longitudinal force is analyzed through calculating the maximum pressure of coupler,together with positive and minus acceleration and longitudinal impulse of train.
