The Smoothed Pseudo Wigner Ville Distribution for the Ship Shafting Torsional Vibration Signals Analysis

Authors

Zou Lülong, Zhang Dapeng*

Abstract
The paper shows the ship shafting torsional vibration signal analysis using the Improved Smoothed Pseudo Wigner Ville Distribution (ISPWVD). The torsional vibration frequency components are complex and signals are variable frequency signals (or more precisely: linear frequency modulated signals, i.e. the whole shafting is constant acceleration or deceleration). The processing method of the torsional vibration signals is introduced in the study. In this paper, it is confirmed that the signal processing method of the torsional vibration is feasible through the actual experiment and has practical significance for the ship shafting torsional vibration analysis.
