Simulation Analysis of End-bearing Performance of Wind Turbine Blades with Different Embedded Structures
The ANSYS finite element software was used to carry out finite element modeling and simulation calculations on the three structural forms of the end face of the blade root of the wind turbine blade,and the influence of different end face structures of the blade root on the bearing capacity was discussed by comparing the response load of the embedded bolt sleeve interface of the blade root under the three structures,so as to provide a theoretical basis for the subsequent design and development of large-scale wind turbine blades.The simulation results show that in terms of ultimate bearing performance,the interfacial load of the embedded bolt sleeve higher than blade root fiberglass end face structure is the lowest,and in terms of fatigue bearing performance,the interfacial load change rate of the embedded bolt sleeve lower than that of the blade root fiberglass end face structure is the smallest.Taking into account both bearing performance and structural process performance,the flush structure of embedded bolt sleeve and blade root fiberglass end face has good practical prospects.
