To analyze the reason for the abnormal increase in wind noise of the vehicle at high speed,the paper employs a seal pressure distribution testing system from the perspective of dynamic sealing.It measures the dynamic indentation of the seals,detects dynamic sealing leaks,and analyzes their impact on wind noise at high speeds,identifying the leakage as the source of the increased noise.By studying the influencing factors of dynamic seal,the research reveals that the excessive deviation of the clearance between door and the vehicle body is a main reason for the loss of the sealing contact.The paper concludes and proposes the diagnosis method for the abnormal wind noise at high speed.
