Abstract

This paper discuss about structure modification method of the reciprocating compressor to reduce its vibration and noise in small refrigeration system. The structure modification is applied using analytic FE models and then applying suggested Component Mode Synthesis(CMS) algorithms. The efficient CMS algorithms to a compressor's fixed base design problem are analytically tried and verified from some experiments.

본 논문은 소형 냉동 시스템에서 왕복동식 압축기는 주요한 진동원이자 소음원으로서 압축기의 외부 구조 동특성을 변경함으로써, 진동과 소음을 줄이는 방법에 관한 것이다. 구조 동특성의 변경은 유한요소 모델에 의한 해석적 방법을 적용하고, 구조 변경의 시도는 두 유한요소들 간의 모드합성법(CMS)을 적용한다. 효과적인 CMS의 적용방법을 찾아내고, 이 방법에 대하여 압축기 모델에 대한 실험적 검증을 통하여 검증하였다.
