Abstract
The membrane coupling plays an essential role in the transfer process of the wind wheel torque. In order to meet the design requirements and get more accurate stress analysis state of membrane, based on the finite element software HyperMesh, membrane and the surrounding model is regularly meshed into hexahedral element, and to MSC.patran analysis platform, to check the strength of the coupling. The result of analysis showed that, the maximum stress and deformation of coupling can be met to the design standards and reach the requirements also. Using of hexahedral element, analysis time of CPU can be reduced and smoother stress and strain contours cloud can be also obtained, so it provides a more scientific basis for the design and manufacture of membrane coupling.
