摘要

UUV systems in operational condition strongly depend on connectingrncables. In this point of view, dynamics of the UUV cable system isrnvery important for operational and safety aspects since a cablerngenerally encounters the great tension. In this study, the analysisrnprocedure for the pre-stressed normal mode vibration problem of UUVrnsupport system was developed. To consider the pre-stress effectrninduced by the weights of launching system, nonlinear static analysisrnwas carried out before the dynamic analysis for normal mode vibration.rnThe characteristics of normal modes of support system and thernvariations of normal modes according to the positions of launcher arernpresented in the analysis results.
