RESEARCH ON 2 MW COMPOSITE NACELLE STRUCTURE OPTIMIZATION

Abstract

Abstract: Due to the anisotropy, compares to metal materials, GFRP composite can performance its advantages better by corresponding design. Composite nacelle is a typical example, the most structure analysis of it is only to check its bearing capacity. According to the Lloyd's GL2010 standard, the model was built by commercial soft SolidWorks, the stiffness and strength are calculated by finite element soft ANSYS. On the basis of the results, the design of the reinforced rib size and the skin thickness are optimized. Limiting condition of manufacture, location of stiffeners, block, cost and other requirements are all in the considering. The structure after optimized was analyzed, and the results show that the analysis and optimization result based on the manufacture, meets the engineering requirements for stiffness more, this worth to be recommended.

Key words: finite element, structure optimization, nacelle-cover
