Wet Modal Analysis of a Deep-Sea Autonomous Underwater Vehicle

Abstract:

When cruising underwater, the Autonomous Underwater Vehicle (AUV) oscillation will affect some sensors’ measuring precision. In this paper, the method of equivalent entities is used to build the AUV’s solid model, and the AUV’s fluid-solid coupling system together with its wet modal is analyzed using ANASYS software. In addition, the AUV’s bending mode and breathing mode under different depths are discussed, which will reflect the changing trends of AUV vibration frequencies during operation. The conclusion can provide the theoretical basis for the AUV structure design when certain measuring task is performed using sensors.
