高速电动车组的发展及其在我国的应用探讨

分析国外300km／h高速动车组发展动态，认为受关键参数的限制，300km／h的速度是一个重要临界值。在此速度之下，动力集中与动力分散两种方式都能适应；在此速度之上，动力分散为佳。提出我国必须坚持科研开发与应用紧密结合的原则，在充分试验并巩固200—250km／h电动车组技术的平台上，应向开发300km／h电动车组技术推进。建议对总体方案进行深入比较后，再确立最佳方案为好。

Probe into development trend of high speed EMUs and applications in China

Development trend of 300km/h high speed EMUs in foreign countries are narrated. 300km/h is considered to be a veryimportant critical value as the speed is limited by some critical parameters. At a speed lower than 300km/h, both power concentration andpower distribution could apply, while at a speed higher than 300km/h, power distribution is preferred. It is proposed to closely combineresearch and development with applications. 300km/h EMUs should be developed when 200~250km/h EMU is fully tested and improved.The optimum scheme could only be defined after deep comparison of general schemes.
