| description | As the size and flexibility of wind turbine blades increase, the aeroelastic challenges faced by wind turbines become more pronounced. To prevent blade damage due to vibration and improve the aeroelastic stability of wind turbine blades, this paper proposes a bionic blade with a bionic web inspired by bamboo and honeycomb structures. The fluid-solid interaction analysis of the blades is conducted using computational fluid dynamics and the finite element method, based on the Shear Stress Transport (SST) k-w turbulence model. The displacements, stresses, strains, modal, and harmonic response analyses of both the original and bionic blades are evaluated underrated operating conditions. The results indicate that, compared to the original blade, the maximum displacement of the bionic blade is reduced by 10.1%, the maximum stress value on the blade surface is 2.1% lower, and the maximum strain value is 2.5% lower. The bamboo honeycomb web buffers wind loads in stages during the vibration and deformation of the bionic blade, leading to reduced vibration displacement and improved deformation resistance. |
