Abstract

Due to the complexity of submarine structures, it has low accuracy for finite element analysis method and time domain correlation method to analyze the vibration signals’ transfer characteristics of structures. Aiming at these problems, a spectral correlation technique is proposed to quantitatively analyze transfer characteristics of structures. And it analyzes the influence on signal components by structures according to the vibration signals from two sides of structures, and avoids the difficulty of accurate finite element modeling and waveform distortion when vibration signals go through the complex structures. The proposed method is applied to analyze the transfer characteristics of a scaled submarine model’s different structures, and quantitative analysis results show that it can analyze the vibration signals’ transfer characteristics of different structures very well.
