高速动车组和客车气密性技术与标准

The Air-tightness Technology and Standards of High-speed Multiple Unit and Passenger Cars

在论述空气压力波对列车的作用和对乘客的影响的基础上,介绍日本、欧洲和我国对高速动车组和客车气密性的要求,以及整车和部件气密性试验方法。总结在高速动车组和高原高寒客车上采取的密封措施。建议对高速动车组和客车的气密性作进一步试验研究,不断完善我国高速动车组和客车的气密性标准。

Based on the influence of air pressure wave on train and passengers, the authors introduce air-tightness requirements of high-speed multiple unit and passenger car in Japan, Europe and China, as well as the air-tightness test method for a whole train and components. Sealing measures adopted in high-speed multiple unit and train running on plateau and frigid regions are summarized. It is suggested that further experimental research should be done for air-tightness of high-speed multiple unit and passenger car, in order to constantly improve the air-tightness standard of China high-speed multiple unit and passenger ear.
