摘要: 
本文主要研究目的軸對稱工件做形狀,使結構在滿足所給得到最輕質量的
設計。本文利用有限單元的三點環狀軸對稱元素建構模型,並對其作位移
、應力的分析。另外再配合三次平滑曲線理論, 以控制點座標當作設計變
數,根據由解析法所得到的靈敏度分析, 用最大剪應力理論做設計限制條
件,以期使結構最輕量化為目標,做形狀最佳化設計。在最佳化方面是採連
續線性規劃法。

The shape optimization of axisymmetric structures is discussed
in this thesis. The objective function is the structural weight
and he maximum shear stress theory is used to setup thehe
axisymmetric triangular ring element models wereanalyze the
nodal displacements and the elementoundaries of the structures
were modeled by cubicordinates of teh interpolation points for
cubicken as the design variables. Analytical stressith respect
to the interpolation points were alsolinearized problem was
solved by SLP(Sequentialing) to get the optimum solution.
