Automotive weatherstrips have the function of isolation of water, dust and noise from outside. Weatherstrips are mainly made of EPDM rubber. In general, however, rubber components tend to change physical properties and shapes after using for long time. In addition, vehicle doors tend to be opened by the effect of external pressure drop at high speed. Therefore wind noise may occur at high vehicle speed. With an effort to minimize the problem, this paper introduces an analytical prediction process to evaluate acoustic isolation according to variety door opening conditions by the Fluid Structure Interaction (FSI) analysis. By using the process of FSI analysis, the shape of the weatherstrip can be predicted. And by considering the aging effect, such as permanent deformation and compression load, it is possible to predict the durability. Also, the acoustic isolation is evaluated by using the Statistical Energy Analysis (SEA).
