| Abstract: | The tidal current energy is an ideal ecological energy with good economic prospects, low development costs and environmental impact. A new type of turbine called rectangle tidal current turbine, which has high energy utilization and good hydrodynamic performance, is researched. The design of a rectangle turbine frame is provided and ANSYS software is used to check the strength of blades and frame structures under operating conditions and extreme conditions. The Screening and NLPQL optimization function are applied to optimize the final structure form. The result of optimization can decrease the weight by 13.3% and have good economic. |
