Structureborne Noise Transfer Analysis Using Pole Parameter Method for Resiliently Mounted Equipment

절점 해석 기법을 이용한 탄성지지 장비 시스템의 고체음 전달 해석

Structureborne noise induced by shipboard equipment is one of the most significant noise source of ships and can be effectively reduced by resiliently mounting them. In this paper, the pole parameter method is investigated for estimating the structureborne noise reduction of resiliently mounted equipment. In addition, we suggest how to evaluate pole parameters from dimensional and material information of each component consisting of resiliently mounted equipment. To validate and discuss the proposed method numerical analysis for single and double resiliently mounted equipment systems using both pole parameter method and FEM have been done.
