Abstract

The floating tidal current power station is used to transfer the tidal current energy into power energy. Because of the complexity of its structure and the particularity of the loads, theories and criterions existed can not be used directly to evaluate the overall strength of the power station. Based on the potential theory, software of Hydrostar is used to simulate the wave loads; and hydrodynamics loads of the turbine are calculated using CFX. Turbine loads are equivalented and transformed reasonably. 'Equivalent rigid shaft' method is used to apply loads on the structure, and plant carrier (floating platform) strength is calculated by finite element method. The calculation results show that methods adopted in this paper can truly reflect features of stress distribution of the support structure, and strength of the carrier satisfies the working requirements of the turbine.
