| 摘 要： | 随着城市的快速发展,部分城市对地铁车辆速度有了更高的要求,尤其是在国家促进城镇化发展的大背景下,市域(郊)铁路的发展、地铁车辆速度的提高使城镇居民出行更加便捷,如120 km/h的地铁车辆,其速度高、发车间隔短、换乘方便,但速度提高会带来其他方面的影响,如噪声、气密性等问题。文章研究地铁车辆气密性的评价标准、评价方法及影响因素,并提出气密性评价指标建议和提升气密性的技术措施。

| Abstract: | With the rapid development of cities,some cities have higher requirements for metro vehicle speed,especially in the context of promoting the development of urbanization,the development of urban(suburban)regional railway and the increase of metro vehicle speed make it more convenient for urban residents to travel.For example,the 120 km/h metro vehicle has high speed,high frequency and convenient transfer and connection.However,the increase of speed will bring other impacts,such as noise,air tightness etc.This paper mainly studies the evaluation criteria,evaluation methods and influencing factors of air tightness of metro vehicles,and puts forward suggestions on air tightness evaluation indexes and technical measures to improve air tightness. |

| Keywords: | metro vehicle pressure air tightness blockage ratio riding comfort rate of change |
