RESEARCH ON STRUCTURAL DESIGN OF 5 MW VERTICAL AXIS WIND TURBINE
Vertical axis wind turbines have gradually become a research hotspot due to their ease of scalability, but the research involving structural aspects is relatively limited.Therefore, a blade and strut composite layup design solution was proposed to meet the structural performance requirements.The com...

| description | Vertical axis wind turbines have gradually become a research hotspot due to their ease of scalability, but the research involving structural aspects is relatively limited.Therefore, a blade and strut composite layup design solution was proposed to meet the structural performance requirements.The computational fluid dynamics method was used to obtain the aerodynamic loads under extreme environments and loaded them onto the wind turbine surface.The finite element method was used to perform the statics and modal analysis.The results show that the proposed wind turbine blade, strut, and tower have sufficient safety under extreme loads.The maximum displacement is located at the top of the blade trailing edge, the maximum stress is located at the connection between the tower and the strut，and the maximum strain is located at the blade web in contact with the strut; the vertical axis wind turbine wind wheel still has strong torsional load characteristics under the windward condition; the wind turbine operating frequency is less than the wind turbine first-order natural frequency, and its relative difference exceeds 10%.The wind turbine will not resonate under rated conditions. |
