Three Dimensional Finite Element

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.

Three Dimensional Finite Element

The three-dimensional finite element numerical model of wind power generator unit is created by using ANSYS. The elastic-plastic constitutive is introduced and the nonlinear contact is set up between the foundation stub and concrete. The different reinforcement arrangement’s impact on structure is researched, the strength characteristic and law of reinforcement concrete is discussed and a more rational scheme is raised. 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 turbines.

Belongs to sub-tropical zone marine climate, the Matsu islands are strongly affected by ocean monsoon and have plentiful wind power with average speed of 4.1-6.3 m/s. According to experiences of vertical-axis wind turbine, MDU has granted the bid of Matsu government’s “Low-Carbon Emission LOHAS (Lifestyles of Health And Sustainability)-type Vacation Islands” project to install two 4kW such generators: all composite patented blades’ design; new design and fabricated generators; remote monitor and merging network. The six-month test after completion of project shows the good efficiency of the whole wind-power generator system, and thus meets the custom’s specifications and also verifies the superiority of our wind turbines.
