摘要
为研究特定编组下长大坡道对货物列车纵向动力学性能的影响,利用SIMPACK动力学分析软件建立列车纵向动力学模型,分析研究了坡道牵引启动工况与紧急制动工况下的列车纵向动力学性能并做了分析对比,经研究认为在牵引启动工况与紧急制动工况下列车的纵向动力学性能均符合要求。
In this paper,in order to study the influence of the long and large ramps on the longitudinal dynamics of freight trains under a specific formation,the longitudinal dynamics model of the train is established by using SIMPACK dynamic analysis software,and the trains under the ramp traction starting conditions and emergency braking conditions are analyzed and studied.The longitudinal dynamics performance has been analyzed and compared.According to the research,the longitudinal dynamics performance of the vehicle under the traction start condition and the emergency braking condition meets the requirements.
