A design and its optimization of a wind turbine platform using the CAE technology

摘要

To design a wind turbine platform should consider both its stiffness and its dynamic properties.Aiming at it has longer fatigue life and relatively less cost.The design concept will be offered by topology technology.Shape and size of the structure will be controlled and optimization by FEM.To find out a better structure,designer should read the real constraints and choose to modify some real constants on the structure.The result reflects that a new design has better performances under the loads while saves the material and costs by 42.1％.This paper develops a new design process combined with CAE and directs the way of modern mechanical design.
