Abstract: Wind power blade root model was built up using Catia, meshed by professional mesh tool, analyzed by commercial FEM software, based on which the FEA result is eventually got. Using the FEA result and load Markov matrix, the root bolt′s damage can be obtained by fatigue code in Matlab. In this article, bolt stress are compared between with and without ceramic gasket, and the impact on bolt fatigue property of gasket is explored. It is indicated that bolt damage is obviously reduced by putting ceramic gasket under the nut from the result of simulation, while fatigue life is effectively elongated.

Key words: wind power blade, ceramic gasket, fatigue, bolt
