日本的新干线诞生于上世纪60年代,其后随着信息技术和电气技术的整体进步,为实现大运量高密度运行、提高安全性能及减少维护费用基本目的,新干线先后做过7次大的设计变更,应用了大批新技术。从技术整体来看,与20世纪60年代相比有了质的飞跃。按照日本“全国新干线铁道整备法”第二条规定,新干线必须在主要区间线路上以每小时200公里的高速行驶。在东海道新干线建设之初,这样的法律就已经定了下来。为了要与一般火车铁道有明显区别,新干线高速铁道建设的这一宗旨就更加明确。经过设计人员坚持不懈地努力进取,新干线从线路、车体的规格到运转、管理等方面,都形成了完整的系统。
Japan’s Shinkansen was born in the 60s of last century, followed by the overall progress of information technology and electrical technology, in order to achieve the basic purpose of high-capacity high-speed operation, improve safety performance and reduce maintenance costs, Shinkansen has done 7 times Large design changes, the application of a large number of new technologies. In terms of technology as a whole, there has been a qualitative leap compared with the 1960s. According to Article 2 of Japan’s National Railway Maintenance Law of the Shinkansen, the Shinkansen must travel at a speed of 200 kilometers per hour on the main section of the route. At the beginning of the Tokaido Shinkansen construction, such a law has been set. In order to have a clear distinction from the general train railway, the purpose of the construction of the high-speed railway in the Shinkansen is clearer. After designers persevere efforts to forge ahead, the Shinkansen from the line, body specifications to operation, management, etc., have formed a complete system.
