Method study of parametric substructure on thin plate with multi-holes

To analyze complex thin plate structure with multi-holes, this paper puts forward a parametric substructure method. According to the method, superelement is established and the number of degrees of freedom (DOF) is reduced greatly by DOF condensation. In the course of numerical calculation, the superelement is loaded directly, unnecessary to disperse the structure any more. For homology structures, superelement can be used by transforming coordinates. Furthermore, the parameterization method makes the modeling and analysis of homology structure much easier. Finally, it is verified that the method is feasible and effective through practical application.
