摘要:
城市轨道交通车辆的废气排放大多采用自然排风方式。当列车最高运行速度由80 km/h提高至120 km/h后，原有的自然排风式废气排放装置在使用中出现了异响问题。分析了城市快速轨道交通项目中车辆废气排放异响问题的原因，结合有限元仿真，提出了相应的对策方案。
Abstracts:
Natural exhaust mode is widely applied in vehicle exhaust emission for urban rail transit. When the train speed increased from 80 km/h to 120 km/h, abnormal sound would occur in the natural exhaust device during operation. The reasons of which are analyzed and corresponding solutions are proposed in combination with finite element simulation.
