收纳高速动车组的《列车牵引计算规程》刍议

Discussion on "Regulations on Railway Train Traction Calculation" Including High Speed EMU

我国开通运营和正在建设的高速铁路里程已双冠全球。中国高速动车组(CRH系列)已规模制造和广泛采用,所以未来修订《列车牵引计算规程》收纳动车组已是大势所趋。动车组与机车牵引式列车的编组不同,是动车(M)和拖车(T)的固定编组,可以直接为列车牵引计算提供在平直道上所有运行工况下的列车单位合力数据。由于彼此的回转质量系数不同,高速动车组和机车牵引式列车虽然均遵循列车运动方程,但具体计算列车加速度、运行时间和运行距离等公式的相关系数存在差异。此外,一些意见和建议可供未来修订《列车牵引计算规程》参考,诸如删节图表、合并机车单位基本阻力公式、深入探究起动阻力、附加阻力(曲线阻力、隧道阻力等)以及系统计算精度等。

The kilometerage of China high-speed railways in operation and under construction are both ranking first in the railway world,and the series CRH of high speed EMU in china are manufactured in batches and widely operated,so the futuristic revised edition ＂ Regulations on railway train traction calculation＂（including high speed EMU）is the trend of the times.High speed EMU differs from locotractive train in formation,high speed EMU is fixed formation by motor car（M）and trailer（T）and can be direct provided data of train unit join difference in rotary mass coefficient between high speed EMU and loco-tractive train,so although they are abided by the same train motion equation,yet corresponding coefficients of concrete calculative formulas for train acceleration and running time and distance should make a difference between each other.In addition,several opinions and suggestions are made for reference to the futuristic revised edition ＂ Regulations on railway train traction calculation＂（including high speed EMU）,such us delete diagram or table;merge locomotive unit basic resistance formulas;deeply research into starting resistance,additional resistances（curves resistance,tunnels resistance,etc.）and system calculative accuracy and others.
