| 摘 要： | 对汽车在使用空调时由空调压缩机引起的两种内噪进行了研究,得到如下结论:(1)在发动机转速为4 750 rpm左右时出现的轰鸣噪声,是由于压缩机支架总成模态频率与发动机二阶振动频率共振引起的;(2)怠速时的拍频声是由于发动机与空调压缩机的传动比不合理造成的拍频现象。

| Abstract: | In this paper,two kinds of vehicle interior noise caused by air conditioner＇s compressor are studied.It is discovered that（1） the booming noise appears when the rotation speed of the engine reaches about 4750rpm,due to the resonance caused by the powertrain modal frequency of the compressor＇s support and the engine＇s second order vibration frequency;and（2） the beat noise of idling is due to the beat phenomenon caused by the irrational speed ratio of the engine and the air conditioner＇s compressor. |
