Wet Modal Analysis of Deepwater AUV System
DUAN Bao-sheng
Abstract：From a new angle of the wet modal analysis of AUV (Autonomous Underwa‐ter Vehicle) ,the characteristics of externally excited frequencies that the AUV which was developed by the major national science and technology projects is possibly subjec‐ted to are studied by means of the commercial software ANSYS .To avoid the resonance of AUV ,the externally excited frequencies that the AUV is subjected to should be much lower than its seventh order natural frequency .Based on this ,the excitation fre‐quencies on the AUV body ,which are produced by the interference sources occurring during the navigation of the AUV ,the mechanical structures carried by the AUV and the accessory structures of the AUV ,are calculated .The calculated frequencies are all lower than the natural frequency of the AUV body ,indicating that the stability of the AUV can not be impacted on .
