作动器在智能桁架结构形状控制中的优化配置

The Optimal Placement of The Actuator for Shape Control of Smart Truss Structures

导出了智能桁架结构静态形状控制方程,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力指标对主动杆件进行了优化建模。

In this paper, quasi-static shape control equations of smart truss structures are presented which are valid in linear elastic range. Generally, the number of the active member is less than that of the truss members. And the placement problem is governed by the control energy and strength requirements. So the model was built to find the optimal placement of the active member with minimum stroke and minimum induced element forces.
