Research on Static Analysis of Box Foundation for Wind Turbine on SESAM Software
The overall finite element model of box floating foundation of a generic 1.5 MW wind turbine which is located in the 35 m depth of Bohai sea is established by the software SESAM. According to the potential fluid theory, the hydrodynamics loads are calculated by the Hydrod module and then the method overall strength analysis and fatigue performance of box foundation of offshore wind turbine are discussed. Air dynamics loads on turbine are solved according to the Betz theory and distribution of stress are calculated with considering application of hydrodynamic load and aerodynamic loads. It is shown that the maximum stress is at the connection of the new box floating foundation with the tower of the SESAM results. It is the fatigued part of the offshore wind turbine.
