Impact of Step Height on Deformation of Foundation for Wind Power Generator System

Abstract:

The three-dimensional finite element numerical model of foundation for wind power generator unit is created by use of ANSYS. The elastic-plastic constitutive is introduced and the nonlinear contact is set up between the foundation stub and concrete. Impact of step height on deformation of foundation is researched, the deformation characteristic and law of concrete foundation is discussed and It’s more rational to consider the contact status and material nonlinearity. The research results offer scientific basis for design and optimization on foundations of wind power generator system.
