薄壁梁的有限元分析及优化

Finite Element Analysis and Optimization of Thin Walled Beams

介绍使用有限元方法,对不同物理形状的结构件进行优化的计算力学领域的应用研究,考虑各种约束条件,分析了各种参数如变形、应力、反作用、体积、特征值和特征矢量的灵敏度。

This paper presents the applied research in computational mechanics for the optimization of shapes of different physical objects using finite element method. Sensitivity of the parameters is investigated such as deformation, stresses, reactions, volumes, eigenvalues and eigenvectors. Different types of constraints were taken into consideration.
