A Study of The Tilt-up Sunroof Wind Noise
자동차 선루프 틸트업 바람소리 연구

Abstract
There are three significant noises from the sunroof while driving. Among them, sunroof tilt-up noise has mainly high-frequency characteristics in the side and rear openings of sunroof. Because of complex structures to operate sunroof, significant flow disturbance makes strong turbulent noise. In this study, sunroof tilt-up noise was predicted by using numerical simulation code and the results were compared with experimental data.
