Analysis of Vibration Fault Characteristics of Lifting Fixture Cutting Operation
Under the working conditions of large feed and deep cut,the cutting piece is prone to break and crash,which will re-duce the cutting efficiency and cause danger to personnel.By extracting the vibration acceleration signal from the time domain and frequency domain,the vibration signal was decomposed layer by layer by using the wavelet packet transform method,and the vibration characteristics of the lifting tool cutting operation under different feed speeds were obtained.The transverse vibration equations of cutting pieces were established to study the mechanism of vibration,and the causes and effects of signal characteris-tics when cutting faults were analyzed.Finally,a suitable vibration reduction strategy was proposed.The research method is of great significance for prolonging the service life of cutting slices and reducing the frequency of cutting faults.
