自适应桁架形状控制中主动杆多目标最优配置

Multi Objective Optimal Placement of Active Members for Shape Control of Adaptive Truss Structures

导出自适应桁架结构静态形状控制方程，这些方程在线弹性范围内适用；一般主动杆件数远小于结构杆件数目，且主动杆件的配置问题取决于控制能量和杆件强度等因素，因此基于最短行程和最小导出内力指标和模态退火组合优化算法进行了主动杆件的多目标最优配置；通过算例分析验证了本文分析方法的可行性和有效性。

In this paper, quasi static shape control equations of adaptive truss structures are presented which are valid in linear elastic range. Generally, the number of active members is much less than that of the truss members. And the placement problem is governed by the control energy and strength requirements. So simulated anealing algorithm is employed to find the multi objective optimal placement of active members with minimum stroke and minimum induced element forces. A numerical example is given to illustrate the validity and effectiveness of this methodology.
