摘要：
In this paper, the noise radiation characteristics of hermetic reciprocating compressor (HRC) are studied. Compressor noise is difficult to investigate because various excitation sources are simultaneously applied. Thus, numerical analysis is performed to identify excitation sources generated by the compression process. Finite element models of HRC are constructed by considering the acoustic-structure interaction. Acoustic propagation can be identified visually by applying each excitation source to the configured finite element models. The analysis and experimental results are compared to confirm the computational simulation methodology. From the analysis results, the HRC noise generation mechanism is verified. In addition, it is possible to investigate the acoustic characteristics of each noise source, which is difficult to identify using experimental methods.
