Dynamic Characteristics Analysis of the Rigid Flexible Coupling Multi-body System of Wharf-cable-dynamic Positioning Vessel
Abstract In order to study the coupling effect of the rigid-flexible multi-body system composed of the dynamic positioning vessel, the wharf and mooring cables in mooring state, the lumped mass method was applied to discretize the mooring cables into lumped mass models for the calculation of the moo...
