A Study on Damping Material Design for Vibration Suppression of the Hatchback Trunk Floor Panel

해치백차량 트렁크의 진동저감을 위한 재진재의 최적설계에 관한 연구

Automobiles should be light and practical to reduce the price of manufacturing and maintaining expense. Hatchback vehicles are far from the silence for its practicality. This paper introduced the effective method of the planning of the asphalt material which applies the asphalt damping material. This paper showed the experiment which restrains the vibration of the vehicle trunk using asphalt damping material and chose the position of damping material using the velocity map and strain energy map and planed the optimum position.
