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.
