带电导体面电荷分布问题与发射阴极的几何因子的计算 - In upper level optimization , the thickness and geometry factors of composite skins and webs as well as other structural dimensions are taken as design variables . then , considering the behavior constraints and the side constraints , the structural mass is minimized by the mathematical programming technique . in lower level optimization , the mathematical programming technique or the genetic algorithm ( ga ) is used to search the practical stacking sequence of composite skins and webs to realize the given thickness and geometry factors from upper level optimization
底层优化设西北工业大学博士学位论文计以复合材料蒙皮和腹板等层合板各分层的厚度(或铺层数) 、铺层角和铺层顺序为设计变量，以层合板的几何因子与顶层优化设计给出的最优几何因子之间的误差最小为目标，考虑层合板厚度和制造工艺性约束，采用数学规划方法或遗传算法( geneticalgorithm ，简称ga )求出底层最优设计变量。 - In sso , the thickness of each stack of the laminate must be integer times as thick as that of single ply , the angle of each stack of the laminate is selected from a set of standard angles , and the stacking sequence can change arbitrarily . when material and ply angles of the laminate are selected , ga is used to giye the optimal laminate that meets the given requirements of thickness and geometry factors
在550中，层合板各分层的厚度必须是单层材料厚度的整数倍，铺层角取作一些标准的角度，各分层在层合板厚度方向上的相对位置可任意变化，利用ga求出满足给定厚度和几何因子要求的层合板最优铺层结构。
