摘　　要：为了研究空调室外机噪声源信号传递到目标点的路径及其传递特性,以某型号家用空调室外机作为研究对象,利用工况传递路径分析方法,通过测量空调室外机不同工况下参考点和目标点处的振动和噪声,对空调室外机的噪声传递路径进行了分析,计算出了空调室外机噪声传递路径的传递特性函数,得到了各噪声源对空调室外机噪声的贡献率,为降低空调室外机的噪声提供了科学依据。Some air-conditioning outdoor unit is given as an example to identify the paths and transfer characteristics of the noise sources. Firstly, the path reference points and target points of the air-conditioning outdoor unit noise were determined based on the noise sources and the corresponding transfer paths. Then, the vibration or noise at these path reference points and target points was measured from operational data under different work conditions. Based on these measured data, the transfer matrix was calculated to describe the transfer characteristics of the paths between references and targets. Finally, the contribution of the noise sources were estimated, which is useful to give some reasonable suggestion for noise reduction.
