An Experimental Approach for Characteristic Rattle Noise Considering the Deterioration Condition of Cockpit Module Materials in the Vehicle

자동차 칵핏 모듈용 시편 소재의 열화 조건을 고려한 이음(Rattle) 발생 특성에 관한 시험적 고찰

It is treated more seriously than ever as the customer requirements are becoming a high-quality and diversification. Among the various elements to affect customer's evaluation of automobile quality, BSR(buzz, squeak, rattle noise) are considered to be a mostly contributing factor. Rattle Noises in cockpit modules are one of the major concerns mentioned above. Recently, measurements of the BSR noise between the parts that make up the products from the perspective that the structural causes. For structures that make up material has not been any consideration of the BSR noise characteristics. The aim of this study is to clarify the characteristics of noise occurrence in vehicle cockpit module that consist of plastic material after measuring noise by rattle special testing instrument.
