摘要 针对开发飞行器大型薄壁件柔性工艺装备系统的需求,对该类新型工装系统运行模式的优化生成问题进行了研究。通过分析系统结构和运行原理建立了系统模型,并根据自生成原理,提出了系统运行模式的优化自生成方法。该方法基于工件自身信息和加工过程自身信息,通过有限元分析与遗传算法相结合的自寻优途径,经过不断自身进化,实现定位/支承阵列的全局优化,克服了传统方法通过外部指令,由操作人员根据经验调整系统运行模式而存在的问题。实例验证表明,该方法可使柔性工装系统中定位/支承阵列布局的拓扑形态和分布密度处于最优状态,从而使系统资源得到最佳利用,为柔性工艺装备系统的高质高效运行奠定了基础。 In order to meet the requirements of aircraft large-scale thin-wall workpiece machi-machining process,location/support array evolved adaptively based on finite element analysis and ge-netic algorithm to achieve overall optimization,which avoided the problems caused by traditionalmethods.Experimental result shows that topological layout and density of location/support array canning using flexible tooling system,self-generation of operation mode optimization was presented by describing system model and self-generation principle.According to information of workpiece and be optimized to make best use of system resources and enhance machining accuracy using this method.
