摘要
以市域快轨A型车为例,对其通过隧道时车内的压力变化进行了仿真计算,对市域快轨车辆的密封性要求提出了建议。分析了市域A型车的密封性特点,并提出了市域A型车主要部件加强密封性的措施。
Taking inner-city rapid rail transit type A vehicle as an example,the simulation calculation of its interior pressure changes when passing through tunnel is carried out and suggestions on sealing requirement of inner-city rapid rail transit vehicles are provided.The sealing characteristics of inner-city rapid rail transit type A vehicle are analyzed,and the measures to strengthen sealing of main parts on inner-city rapid rail transit type A vehicle are put forward.
