该标准与旧标准相比首先是名称改为《地铁车辆通用技术条件》,以适应目前城市建设的需要。其次是根据近年来地铁车辆技术的发展,积极采用国际标准和国外先进标准,使新标准的整体水平达到了国际先进水平,新标准在车辆重量、轴重差、列车冲动、车辆密封性能、空气系统的气密性、车体强度的有关指标中,根据近几年车辆技术的发展趋势,采用了国际通用的参数,增强了其适用性和先进性。新标准在追求技术先进性的同 The standard compared with the old standard is first changed to “General technical conditions of subway vehicles” to meet the needs of the current urban construction. Secondly, according to the development of metro vehicle technology in recent years, the international standards and advanced foreign standards are adopted actively so that the overall standard of the new standards will reach the international advanced level. The new standards will be applied in the fields of vehicle weight, axle load difference, train impulse, vehicle sealing performance, System of airtightness, body strength of the relevant indicators, according to the development trend of vehicle technology in recent years, the use of internationally accepted parameters, enhanced its applicability and advanced. The new standard in the pursuit of the same advanced technology
