摘　　要：冰箱压缩机是冰箱制冷系统中最重要的部件之一,同时也是冰箱系统噪声的主要来源。要改善冰箱系统噪声问题,需要结合压缩机本身及冰箱系统优化,因此研究冰箱系统的传递路径显得尤为重要。为了寻求减小压缩机噪声的方法及压缩机结构的最优化设计,需对冰箱系统噪声两条重要的传播路径,即结构和空气传播路径进行分析研究,探究压缩机单体与系统匹配关系,及两条传播路径的形成机理及控制方法,以支持后续冰箱系统噪声的优化和改善工作。通过TPA传递路径分析,分别对五条路径传递的噪声贡献量进行分析探究,并得出各传递路径贡献度评估排序。The refrigerator compressor is one of the most important components in the refrigerator cooling system,and it is also the main source of noise in the refrigerator system.To improve the noise problem of the refrigerator system,both the compressor itself and the refrigerator system need to be optimized.Therefore,it is especially important to study the transmission path of the refrigerator system.In order to seek methods to reduce compressor noise and optimize compressor structure design,it is necessary to analyze the two important transmission paths of noise in the refrigerator system,structural and air transmission paths.The matching relationship between the compressor and refrigerator system,as well as the formation mechanism and control methods of the two propagation paths,were investigated to support the subsequent optimization and improvement of refrigerator system noise.Through TPA transmission path analysis,the noise contributions of the five paths were investigated,and the evaluation results of the contribution of each transmission path were ranked.
