Dynamic Traction Load of a Multi-mass EMU Braking Model

摘要

摘要: 针对单质点模型不足以准确描述动车组制动情况的问题,根据多质点动车模型的制动力分配,建立了动车多质点制动模型.推导出多质点模型在制动工况下的基本阻力和附加阻力以及推算出牵引网侧时变功率,对多质点模型动车组在平直轨道、有坡道和弯道情况下进行制动过程仿真.通过仿真结果与动车制动实测数据的比较,其距离误差小于50 m,验证了多质点模型的准确性.

Abstract: As single-mass model of an EMU (electrical multiple units) model can not exactly describe vehicle braking performance, a multi-mass EMU model was established according to braking force distribution. Basic resistance, additional resistance and the time-varying power of traction network were deduced, and the EMU braking situations with common rail, ramp and curve were simulated. In contrast to the measured data,the distance error of the multi-mass model is less than 50 meters, which demonstrates the accuracy of this model.
