[ 摘要] 根据优化变量不同,结构优化可以分为拓扑优化,形状优化和尺寸优化三个层次。Ansys 的
Design Opt 优化处理器和 Topology Opt 优化处理器可以方便的进行上述三类变量的优化。本
文建立了壳体结构拓扑,形状和尺寸一体化优化的方法,提出了 Ansys 环境下壳体结构拓扑,
形状和尺寸一体化优化的实现途径,算例验证了该计算方案的有效性。

[ Abstract ] According to design variables, structure optimization consists of topology optimization,
shape optimization and size optimization. In ANSYS software, Design Opt and Topology
Opt could deal with them effectively. In this paper, firstly, an intergrated approach to
topology, sizing and shape optimization is formulated for shell structures . Secondly,an
calculating scheme is proposed based on both Design Opt and Topology Opt. An example
show the effectiveness of the approach.
