Abstract:
The shape-form analysis and load analysis were done by nonlinear FEM. On the basis of surface FEM grid nodes, geometry property research of structure curved surface was progressed, including normal vector, GAUSS curvature, mean curvature and principal direction vector. In this process, the approximate expression of surface didn't need to be known. The research of surface geometry property was useful for the optimization of analyzed method, the selection of cutting pattern mode and the analysis of cutting pattern error. The results show that the geometry property of structure curved surface can be gained by the method and will help to design this kind of structure.
