摘要
以内力为设计变量，构造了多工况作用下空间桁架结构的拓扑优化模型，利用凸规划的对偶理论，可转换成以Ｌａｇｒａｎｇｅ乘子为变量的二次规划，再以可分离变量的子二次规划进行逼近，用解析法即可求解，实践证明，该方法很有效．
In this paper,the member forces are considered as design variables,and the topological optimization mod- el for space trusses is given under multiple loading conditions,By using dual theories in convex analysis,it is converted into a quadratic programming about Lagrange multipliers,then approximated by some quadratic programmings about separate variables,solved by analytic method. Many examples show this method is very effective.
