摘要

车辆密封性能是影响乘客舒适性体验的关键因素，而车门系统密封性能的优劣直接决定了车辆的密封性能，因此提升车门密封性意义重大。通过分析影响车辆密封性能的阻塞比、车辆运行速度等因素，结合舒适性评价标准，针对塞拉门系统密封性能的提升进行了研究。文章提出了增加约束限位和改进胶条断面等方式实现车门系统密封性能优化，并通过台架充压试验进行对比验证。结果表明，在门扇下部增加约束和气动压紧锁的方式能显著提升车门系统的密封性能；采用反向唇边的非对称式护指胶条对提升车门系统密封性也具有一定效果。研究成果可为系列化中国标准地铁列车车门系统的密封结构设计提供指导建议。

Abstract

The sealing performance of the vehicle is the key factor affecting the comfort experience of passengers

and the sealing performance of the door system directly determines the sealing performance of the vehicle. Therefore

it is of great significance to improve the sealing performance of the door. The factors affecting the sealing performance of the vehicle were analyzed

such as the blocking ratio and the running speed of the vehicle

and the improvement of the sealing performance of the sliding plug door system was studied combined with the comfort evaluation standard. The method to optimize the sealing performance of the door system by adding restraint limit and improving the rubber strip section was proposed

which was verified by bench pressure charging test. The results show that the sealing performance of the door system can be significantly improved by adding constraints and pneumatic pressure locking at the lower part of the door leaf

and the asymmetric finger protection rubber strip with reverse lip edge also has a certain effect on improving the tightness of the door system

which provides guidance and suggestions for the sealing structure design of door system of serialized China standard metro train.
