압전제어를 이용한 차량소음의 판넬기여도 시험방법 개발

A new panel contribution analysis(PCA) method based on panel vibration control with several piezoelectric actuators has been suggested in order to identify the noise contribution of vehicle panels while driving. This method has an advantage in short test time compared to the conventional PCA method, since it doesn"t need to measure the acoustic transfer function on each panels. Besides this enables us to test the contribution of each panel simultaneously on driving. In this paper, we verify the validity of this method.
