不久前，ＳＳ８型电力机车在铁科院环形线上创造了２１２．６ｋｍ／ｈ的运行速度新记录，这表明我国已初步具备研制高速车的工程基础。本文仅根据高速动车组几种不同编组方案，讨论在给定剩余加速度值、运行最高时速为２００ｋｍ工况下，非电气化特别繁忙区段采用内燃机车作为动车组头车等动车组编组方案时动车组的牵引功率。并从牵引计算出发，列出数种动车组编组方案的相应计算结果。进而导出内燃动车组的功率、重量、最高运行速度、剩余加速度之间的基本关系公式。本文可为内燃动车组的开发和动车组的总体可行性设计提供若干依据。
Not long ago, SS8 electric locomotive created a new record of operating speed of 212.6km / h on the ring line of ASTRI, which shows that our country has initially possessed the engineering foundation for developing high-speed vehicles. In this paper, only based on several different high-speed EMU grouping program to discuss the given residual acceleration value, the maximum operating speed of 200km operating conditions, the non-electrified special busy section of the diesel locomotive as the EMU head car and other EMU formation program when EMU Group traction power. Starting from the traction calculation, the corresponding calculation results of several EMU marshalling schemes are listed. And then derive the basic relationship formula between the power, weight, maximum operating speed and residual acceleration of the internal combustion unit. This article can provide some basis for the development of EMUs and the overall feasibility design of EMUs.
