回转质量系数对高速列车牵引电算的影响

高速铁路电动车组在列车编组方式、牵引及制动性能、列车运行控制模式等方面与普速铁路旅客列车有着较大区别。本文以高速动车组列车牵引计算特点分析为基础,从回转质量系数因素阐述了高速列车牵引计算指标参数的影响,并推导了基于回转质量系数的高速列车加速度、运行时分、加速距离及制动距离等指标国际单位制表达式,最后以CRH3型动车组及京津城际铁路线路纵断面为依据,进行模拟计算分析得出回转质量系数对牵引计算指标的影响规律。

Influence of Rotary Mass Coefficient in High Speed Train Traction Calculation

There is a clear difference between high-speed and common passenger train in marshalling way,traction and braking performance,train operation control mode etc.The paper analyz the characteristics of high-speed EMU train traction calculation,then,after expounded the influence of high speed train traction calculation at the aspect of rotary mass coefficient,the paper deduced the International units expression,such as acceleration,operation hours,acceleration and braking distance.In the end,according to the simulation and analysis with CRH3 type EMUs and the vertical section of Beijing-Tianjin inter-city railway line,the paper draw the conclusion that the rotary mass coefficient has a measure of influence in high-speed train traction calculation.
