Finite Element Analysis of Elastic Support Performance of Wind Turbines
摘要
Abstract
The nonlinear mechanical property of rubbers can directly affect the vibration reduction performance of elastic supports of wind turbines. In this paper, the experimental data of rubber tension and compression tests is fitted by finite element analysis software, and an optimal rubber constitutive model is derived. According to the working condition of the elastic support, reasonable working parameters and material parameters of the rubbers are selected to establish the global model, a quarter of the model and the axisymmetric model for the elastic support of the wind turbines. Then, the three models are calculated and the results are compared carefully. The quarter of the model is selected to analyze the performances of the elastic support, such as the nonlinear vertical stiffness, lateral stiffness and natural frequencies and so on. The experimental results show that the finite element analysis is effective. The work is of significance for design of new elastic supports of wind turbines.关键词
