铁路干线运用的车辆,在强度、工作可靠性和安全性方面应与现代和未来的运用条件相适应。这些条件是由在综合运用经验和科技成就的基础上拟定的文件规定的。同时对车辆车体和走行部分的承载元件予以特别注意,因为主要是这些承载元件决定着车辆的运行安全性。到目前为止,在制定电动车新结构时主要的标准文件还是:对于动车—1968年由全苏车辆制造科学研究院制定的,轨距1524毫 Vehicles used on railway lines should be adapted to modern and future conditions of use in terms of strength, operational reliability and safety. These conditions are set out in documents prepared on the basis of a combination of experience and scientific and technological achievements. At the same time special attention is given to the load-bearing elements of the vehicle bodywork and running gear, since mainly these load-bearing elements determine the operational safety of the vehicle. So far, in the development of the new structure of electric vehicles the main standard document is: For motor cars - 1968 by the All-Soviet Vehicle Manufacturing Institute of Science and Technology, gauge 1524 milliseconds
