摘　　要：针对旋叶式压缩机的启动噪声,对压缩机系统进行了试验、分析和改进。在半消声室中搭建了噪声测试试验平台,测试了压缩机的启动噪声,分析了压缩机的启动机制。提出了控制启动噪声时长的措施,试验测试不同球阀结构及离合器结构对压缩机启动噪声的控制效果,并在整车上对球阀结构与离合器结构的控制效果进行了试验验证。结果表明:旋叶式压缩机的启动噪声是不可避免的固有表征;通过优化压缩机球阀结构及离合器结构的控制方法能够有效缩短启动噪声时长1~2 s。Aiming at the problem of starting noise in rotary vane compressor,a compressor system is tested,analyzed and improved.Firstly,the noise test platform is built for the test of the rotary vane compressor starting noise in a semi-anechoic chamber,and the starting mechanism of the compressor is analyzed;Then,measures to control the starting noise duration are proposed,and the control effects of different globe valves and clutch structures on the starting noise of the compressor are tested respectively;Finally,the control effect of different globe valves and clutch structure is verified by experiment on a real car.The result shows that the starting noise of rotary vane compressor is an inevitable inherent characteristic;Through the control method of compressor ball valve structure and clutch structure,the starting noise duration can be effectively shortened by 1~2 s.
