摘要
声振传递路径分析是噪声根源分析的一个行之有效的方法。文中针对某空调室外机,分析振动对噪声的影响,从减振的角度控制噪声。针对压缩机低频运行工况,建立传递路径分析模型并开展试验研究。根据试验结果识别出空调室外机噪声的主要传递路径,找出主要传递路径贡献量大的具体原因,为空调室外机噪声控制提供依据。
The transfer path analysis of sound and vibration transmission is an effective method to improve the noise performance of mechanical structures. To suppress vibration and noise of an air conditioner outdoor unit under low frequency, a transfer path analysis model was established, the path analysis experiment was carried on. According to the experimental results, the main transfer path of the noise of the air conditioner outdoor unit was identified, and the main reasons of the contribution of the main transfer paths were found out. The results provide the basis to optimize the noise performance of the air conditioner outdoor unit.
