摘要：

自然界的生物结构在自适应生长规律的控制下形成了既没有不承载区，也没有过载区的最优材料布局形态，基于这种自适应生长规律原理的SKO（soft kill option）方法可用于工程结构的拓扑优化设计。深入探讨了基于满应力准则的SKO原理的实现方法，并着重讨论了结构拓扑形态寻优过程中的设计参数、寻优策略等关键技术，以若干典型的设计实例说明了该方法的有效性。

关键词: 满应力准则;SKO;结构拓扑优化;仿生设计

Abstract:

All of biologic structures in nature are perfectly optimum structures under the control of their adaptive growing rules in which neither over-loaded nor non-loaded areas exist. The SKO method that is on the basis of the similar adaptive growing rules can be applied to the structural topology optimization to obtain the optimum layout of material in engineering structures. The full stress axiom was used as the SKO design criteria, and the implementation approach of SKO method was studied. Moreover, the design strategies and parameters were discussed in detail. Some typical examples were studied to demonstrate the validity of the suggested proposal.

Key words: full stress axiom, SKO(soft kill option), structural topology optimization, bionic design
