| 摘 要： | 在结构形状优化设计中,建立了轴对称问题的边界元理论公式,与不带轴对称问题的边界元理论相比较,它优化了计算效率,且提高了设计效率,并将该理论公式与通用的优化设计算法相结合,建立了一种新的优化设计方法.用这种新算法对二维平面应力下的弹性体进行形状优化,获得满意的结果.

| Abstract: | The boundary element formulae of axial symmctric problems are derived in optimal design of structural shapes. Compared with the asymmetric problems, these formulae optimize computational method and raises the design efficiency.A new optimal design is established by combining this method with conventional optimal design algorithm.The new algorithm is used to make a shape optimization for elastic body subjected to two-dimensional plane stress and is proved to get satisfactory results. |
