摘　　要：压缩机的噪声辐射是通过壳体的振动辐射出去,为了降低压缩机的噪声,并进一步优化壳体的声学特性,利用数值模拟方法,在合理简化模型的基础上,进行了壳体模态分析。然后,研究不同的参数(泵体支撑方式,集中力作用方向,壳体形状、厚度和阻尼)对壳体噪声辐射的影响,给出有效降低壳体噪声辐射的方法,其分析结果给压缩机壳体的设计与优化提供重要的参考依据。The compressor noise radiated by shell vibration. Therefore, based on the reasonable model, shell modes were extracted and applied to numerical simulation method for noise reduction of compressor and improvement of shell acoustic performance. Then, a number of effects were studied, including the support method between shell and pump, the direction of concentrated force, and the shape and thickness and damp of shell. Some methods which can reduce the noise radiation of shell effectively were given out.
