Free Vibration Analysis of the Scroll Compressor Housing by Shell Theory

셸이론을 이용한 스크롤 압축기 하우징의 자유진동해석

In this study, the Rayleigh's energy method and the Rayleigh-Ritz method on the basis of Flugge's shell theory was used to analyze the dynamic characteristics of the scroll compressor housing with clamped boundary condition. The frequencies and mode shapes from theoretical calculation were compared with those of commercial finite element code, ANSYS. In order to validate the theory, modal test was also performed by impact test and FFT analysis.
