Wind turbine blades load matching method under biaxial fatigue test

In order to improve the fatigue test accuracy and efficiency of full-scale structure wind turbine blades, an effective load matching method for blades under biaxial loading is proposed. The blade scheme designed. transfer matrix used calculate bending moment loading. particle swarm optimization algorithm designed optimize position mass excitation device in flap-wise edgewise directions position, quantity fixed counterweight. Based on this, calculation model data target are integrated into achieve optimal load, Finally, a numerical example given verify it. results show that this can make closer further accelerate popularization test, provide certain theoretical reference application value engineering practice.
