Abstract：According to the wind noise analysis in the process high speed running of certain models rolling window frame structures， from the door sealing strip and sheet metal and the side surround match state， the article compares the sealing structure， finds out the wind noise and reason and establishes improvement scheme， solves the wind of the problems of car door sealing strip， and concludes that the subsequent new models similar to match the structure optimization design.

Key words：high speed， door sealing strip， wind noise
