Anti-Vibration Pad의 실험, 해석 및 설계 방법 확립

Abstract

자동차의 Floor에 부착되는 제진재(Anti-Vibration Pad)는 차제의 진동을 저감하고 차량의 실내 소음을 줄이는데 하는데 중요한 기능을 하는 부품이다. 따라서 적절한 위치에 적합한 제진재의 사용은 최적의 NVH 성능을 얻기 위해 필요하며 경량화와 원가 절감에도 영향을 준다.그러므로 보다 나은 성능의 제진재를 설계하기 위해서는 Foolr에 부착되어진 제진재의 제진 성능 해석과 시험 기술의 확립은 필수적이다. 그 첫 단계로 Beam울 이용하여 여러 온도 조건에서 손실 계수(Loss factor)을 측정하는 방법을 확립하고, 유한요소법(FEM)과 경제요소법(BEM)을 이용하여 평판의 진동에 의해 방사되는 소음을 해석하는 방법에 대해 연구하였다.

The damping sheet called an anti-vibration pad acts an important role in reducing the vibration level of the floor of an automobile. During applying the damping sheet to the floor, decision of the optimized location and appropriate material of the damping sheet is a main aspect considering several design variables such as cost, performance and weight of it. Therefore establishment of the analysis ability and the test skill of the damping sheet to the floor is essential for the better design of it. As a first step of this research, to find the loss factor of it, the methodology of the test scheme has been introduced using specimens of beam for various temperature environment. And the fundamental analysis technique has been studied for the radiation of a panel with the help of the Finite Element Method and the Boundary Element Method.
