In this paper,the partial coherence analysis method for the identification of loader cab's noise sources is introduced.The calculating formula derived can be used to quantitatively analyze each dependent input's effect on the output.Based on the calculating formula,the method is successfully applied to the identification of loader cab's noise.

In this paper,the noise of the cab of the ZLM50B loader was studied with modern signal process technology.The result of the study shows that spectrum analysis and correlation analysis are useful in noise identification and control of construction machinery and equipment.They are of high application value in reducing vibration and noise of construction machinery and equipment.
