基于MBD的飞机钻铆机器人离线编程技术研究

摘要

为了提高飞机钻铆机器人离线编程的效率和质量,提出了基于MBD的智能离线编程技术.依据飞机钻铆的工艺特点构建了钻铆MBD模型,从钻铆MBD模型中自动提取待加工孔的坐标、法矢、材料、紧固件规格等工艺信息,据此规划最佳的机器人加工站位、加工路径和加工工艺参数,并利用CAA基于DELMIA软件开发了飞机钻铆机器人离线编程系统.%In order to improve the off-line programming efficiency and quality for aircraft drilling and riveting robot,an intelligent off-line programming technique based on MBD is proposed.A drilling and riveting MBD model is built according to process characteristics of aircraft drilling and riveting.Coordinates,normal vectors,materials,fastener specifications,and such process information of holes to be drilled are extracted from the drilling and riveting MBD model,and the best machining stations,paths and process parameters are planned according to them.The off-line programming system for aircraft drilling and riveting is developed by CAA based on DELMIA software.
