Study of Deflector Vibration on Panoramic Sunroof

摘要

The panoramic sunroof is a roof system that can be opened and closed. It helps the vehicle to ventilate and provides a wide open feeling. However, when the moving glass is opened during driving, a buffeting noise is generated in the cabin. To solve this problem, a deflector is applied. In this study, we analyze the correlation between the vibration of the deflector and the buffeting noise, and confirm the cause of the deflector vibration and present a structure that can improve it.
