- Abstract
- Mono-pile foundation of offshore wind turbine was simulated using ANSYS finite element software, conducted quasi-static analysis of the foundation of the offshore wind turbine considering the interactions of environmental load, such as wind, wave, current, etc, optimized the size of the pile based on zero-order method. The wall thickness of the pile was reduced under the premise of ensuring displacement, stress, and stability requirements, the total volume of the pile foundation decreased by 33.5% in order to reach the aim of light-duty design; Combining with the variation of the objective function, design variable and state variable in optimization process, proposed that the displacement of pile top is the primary limiting condition, the optimization of shape topology should be taken into consideration while designing the structure; The wall thickness in some parts of the pile foundation can be appropriately reduced to make full use of the strength of the material, under the premise of ensuring top pile displacement.
