Optimization on BCC Lattice Structure and Its Anti-collision Application
In order to study the application of optimized BCC lattice structure in single pile foundation collision of offshore wind turbine,an anti-collision device model is designed.Firstly,based on the Workbench analysis platform,the unit cell size of the BCC lattice structure is optimized by multi-objective method,and the simulation results before and after optimization are compared to verify the reliability of the optimized size.Subsequently,the equivalent model of BCC lattice structure is established by using the asymptotic homogenization theory,and the simulation performance of the anti-collision device model of single pile foundation of offshore wind turbine in collision is compared and analyzed.The research shows that the anti-collision device not only has buffering property,but also can effectively reduce the damage degree of single pile foundation after collision.
