摘　　要：针对飞行器大型薄壁件加工的技术难点,开发了基于机器人操作的智能柔性工艺装备系统。通过分析系统结构和运行原理,建立了数学模型,提出了多点定位的自适应优化方法。该方法根据给定的加工轨迹,自适应地调整柔性工装系统的定位/支承分布,保证总体加工变形趋近最小。实例验证表明,该方法可以使柔性工装系统的支承分布处于最优状态,实现对系统资源的最佳利用,满足飞行器大型薄壁件的高速高精度加工需求。Intelligent flexible tooling system manipulated by robots is developed to solve problems in aircraft large-scale thin-wall workpiece machining.Adaptive optimization of multi-point location is presented by describing system structure and work principle,then we establish mathematical model.This method adjusts location/support array of flexible tooling system according to specified cutting path adaptively.Experimental results show that support distribution can be optimized to make best use of system resources,which improves quality and efficiency of aircraft large-scale thin-wall workpiece machining.
