【摘要】 详细分析了桁架结构布局优化问题的复杂性 ,指出了其中存在的难以解决或常被忽略的问题。主要包括四个方面 :基结构的建立机制 ;有效的结构布局优化统一模型 ;桁架拓扑优化中的杆件删除和恢复问题及拓扑形式的判别 ;结构重分析困难等。论述了这四个关键问题的重要性、现状和解决时遇到的困难 ,并指出这四个问题的解决是实现“智能自适应求解桁架布局优化”的关键所在更多还原

【Abstract】 The complexity of the layout optimization of truss structure is analysed in this paper.The aspects aluays neglected are discussed,such as the forming of ground structure,the effective unified model of the layout optimization of truss,the cut and resume of pole and distinguishing of topolgy form,the difficulty of repeated analysis of structure.All above four aspects are keys to realize intelligently adaptively solving layout optimization of truss.更多还原
