摘要
Abstract
The sensitivity analysis plays a critical role in super large-scale optimization problem.The analytic method for sensitivity analysis has been investigated deeply,and the analytical expression of differential stiffness matrix is derived for shell elements and the displacement constraints sensitivity is obtained by using virtual displacement method.The method was programmed based on the HAJIF system with FORTRAN language.Validation examples showed that the proposed method has a high reliability in solving super large-scale optimization problem,and the efficiency of the present method is almost 70 times of that of the differential method.关键词
