Finite Element Method Mechanical Characteristics Analysis of Tower Foundation for Wind Turbine Generator System

By using ANSYS software, the finite element model of the foundation for wind turbine generator system is built. On the basis of concrete elastoplastic constitutive, the non-linear contact between the foundation stub, a steel part, and foundation concrete is introduced, the internal mechanical characteristics and law of the foundation which is under the influence of wind with unfixed direction are researched on. The interaction state is attained. The numerical analysis considering the contact status and material nonlinearity is more reasonable and the research results offer scientific basis for the domestic autonomous designing and optimizing.
