摘要
为了减少航空薄壁件的定位变形,提出了一种基于0-1整数规划的定位布局优化方法,并对适应自动钻铆的预装配工装的内型卡板布局进行了优化设计。该方法基于"N-2-1"定位原理,将布局优化问题转化为0-1整数规划问题;以对薄壁件定位系统参数化建模分析得到的薄壁件最大变形量最小为优化目标,建立定位布局递推优化模型;采用分步求解的策略,通过混合粒子群算法对薄壁件进行定位布局优化。
In order to reduce the localization deformation of aircraft thin-wall components,the layout optimization method is proposed based on 0-1 integer programming.The method is used for aircraft skin pre-assembled to accommodate automatic drilling and riveting.Firstly,the layout optimization problem is transformed to 0-1 integer programming problem on the basis of the“N-2-1”position principle.Secondly,the optimization model of location layout recursive is established taking the minimum of maximum deformation of thin-walled parts as the target of optimization.The maximum deformation is obtained through parametric modeling analysis of thin-walled parts positioning system.Finally,the layout optimization is fulfilled using the hybrid particle swarm optimization algorithm through stepwise solving strategy.
