Denoising Extraction of Impact Fault Components of Synchronous Hydraulic Motor Based on Displacement Superposition Method
Synchronous hydraulic motor often works under high load condition and on-line fault monitoring can effectively avoid serious safety accidents and economic losses.In order to improve the accuracy of fault monitoring,an adaptive noise reduction and extraction method of fault components of synchronous hydraulic motor based on improved dislocation superposition method is proposed in this paper,and the acoustic signals of gear wear state of synchronous hydraulic motor are studied.The experimental results show that this method has good noise reduction and extraction effect on the impact fault sound signal of synchronous hydraulic motor gear wear state.
