Computational research progress in applied science and engineering
Preserved Fulltext
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
