Research on the Control of GEHPs Vibration and Noise

摘要：

For the noise reduction of GEHP,in this paper,the actual noise of a GEHP is detected firstly,and then the noise spectrum is analyzed.According to the result of the noise spectrum analysis,the project to reduce noise and vibration by using acoustical enclosure is confirmed.The simulation of the noisy level of a GEHP with and without acoustical enclosure by the RAYNOISE software has been finished.And according to the result of the analysis,it can be concluded that,acoustical enclosure can reduce the noise of GEHP obviously,especially for the medium-high frequency noise,but not for the low frequency.
