| Abstract: | The principle and advantages of the sound-intensity-based method for the determination of the radiation noise of engi- neering machinery are introduced in the paper. In the light of the standard of GB/T 16404-1996, the p-p sound intensity tech- nique is used to test the radiation noise of ZL50G type of loader, with the power degree of the main noise sources and the radia- tion noise of the whole loader obtained, the characteristics of the noise in radiation spectrum-analyzed, and the main frequencies of the noise identified. The paper provides an important basis for the tests on and the prevention of the radiation noise of the loader. |
