基于机电耦合的自适应桁架结构最优拓扑控制

以自适应桁架结构为研究对象，发展了结构拓扑优化的理论，并将其应用于自适应结构的最优拓控制之中，首先求出了结构在设计荷载作用下的最优拓扑，然后考虑了两种情况下结构的拓扑重构，其一是结构同时又受到一随机外载的作用；其二是结构中某一在役单元突然失效，算例表明了方法的正确性和有效性。

Research on Optimal Topology Control of Adaptive Truss Structure Based on Mech- Electric Coupling

Adaptive truss structure as research object, the theory of structure topology optimization has been developed, and been applied in the optimize topology control for the adaptive structure. Above all, the optimize topology of structure is computed under the case of the design load, then the structure's topology recombination is considered in two conditions: one is that the structure is acted with another exterior random load; the other is that one of the active element in structure becomes disabled suddenly. The example indicates the method is correct and effective.
