摘要
依据我国高速铁路分相区长度设置规定,总结各型动车组自动过分相的差异,确定动车组过分相时无电运行走行距离的计算方式。在此基础上,分析动车组自动过分相最低入口速度与分相区长度设置、动车组自身运行阻力、坡道等附加阻力的关系,通过数学模型仿真计算得到在GFX装置过分相和ATP过分相两种条件下动车组通过典型坡道的自动过分相最低入口速度结果,给出了动车组自动过分相最低入口速度的通用速度等级。
Based on the neutral section zone regulations of high-speed railway,this paper summarizes the differences of automatic passing neutral section of each type EMU,and determines the distance calculating method about passing neutral section without power.Then the relationship of the minimum acceptable speed of automatic passing neutral section with the distance,the running resistance of EMU,and the additional resistances is discussed in this paper.By the mathematic model,the minimum acceptable speed results are computed on the conditions of GFX device or ATP equipment.
