摘要:随着我国城市化进程的不断加快,随之而来的是城市常住及流动人口的骤增,所以现在中国城市的交通面临着前所未有的挑战,同时也带来了巨大的发展。高铁列车有着准时、便捷、高速、能耗低、污染少等诸多优点,以迅雷不及掩耳之势在人们的日常生活中占据着越来越重要的地位。我国的高铁线路四通八达,遍布全国,连接了500多个城市,高铁列车已成为人们出行首选的的交通工具。而高铁列车中最重要的部分就是制动系统——列车的制动性能事关列车的安全和运输能力。高铁列车已经步入电空制动的时代,目前国外在电空制动的发展上领先于中国,德国的KNORR公司以及日本的NABCO公司是其中的佼佼者,国内现在已经从早期的进口这两国的技术逐步转变进入到了自主研发的过程。81421

The simulation of electric pneumatic braking system of 500km/h-speed High-Speed Rail
Abstract:With the speed-up of urbanization process in China, rural population is shrinking sharply, which comes along with the continuous increasing in the permanent residents and floating population in urban areas, this brings both unprecedented challenges and golden opportunities for the transportation of major cities in China。 Compared to transitional ground transportations, High-Speed Rail (HSR) has advantages of punctuality, convenient, fast, energy efficiency and environmentally friendly, which makes it a more and more important means of transportation in a short period of time。 Nowadays the HSR is all over the country, it connects over 500 cities in China and has already become preferred means of travel for most Chinese。 As the most vital part for HSR, the brake performance is closely related to the safety and capacity of the HSR。 Today's HSR is already in a new era of electric pneumatic braking, and some foreign technologies in this field are ahead of those in China, the KNORR in Germany and NABCO, for example, are two major players in the international market。 Chinese scientists started studying in this field by importing technologies from Germany and Japan in the first place, and gradually we started our own independent research and development in recent years。
Key Words:High-Speed Rail(HSR); braking system; electric pneumatic braking
