Description
Summary:碩士 === 國立中山大學 === 機械工程研究所 === 82 === The purpose of this study is to investigate the optimum design of geometrically nonlinear structure by means of multilevel optimization method with sensitivity analysis. In this study the tangent stiffness method is used to solve the nonlinear problem. The Jacobian conjugate gradient, an iterative solution algorithm, is employed to promote the performance of finite element analysis for structure. The proposed solution procedures are programmed in FORTRAN for implementation on vector-parallel supercomputer CONVEX C3840. The difference of weight optimum design between linear elasticity and considering the geometrical nonlinearity behavior from large displacements are discussed. The suitable tolerances for tangent stiffness method and Jacobian conjugate method are proposed. And the results of examples are presented. Further discussion and suggestions for the results are also stated.
