汽车车门密封性能控制与风噪声改善

摘要

Seal performance of automobile doors is one of the important influencing factors for vehicle’s wind noise level. In this paper, the seal mechanism of main components of automobile doors was analyzed. The relevant methods for noise-leak control were presented. Taking the noise-leak problem of the rear door of a SUV automobile, the abnormal wind noise was eliminated through the seal optimization of the door. The improvement targets in both subjective evaluation and objective testing were achieved.%汽车车门密封性能是整车风噪声水平的重要影响因素，分析汽车车门主要部件密封机理，提出相应泄漏控制方法；结合某款SUV车型后侧窗风噪“泄漏声”问题，通过车门密封优化，消除异常风噪声，主观评价及客观测试均达到改善目标。
