【摘要】 为了实现飞机装配过程的数字化、自动化和柔性化,设计、架构了面向某型号飞机大部件调姿、对合及精加工的装配过程数据管理系统.该系统以工作流驱动的任务管理器为基础,采用扩展的C/S多层架构体系.通过分块读写思想、参数化策略和Oracle在线存储与XML离线存储并存的双重机制,实现了数据的高效存取.详细阐述了过程数据集成的若干关键技术,包括测量与状态数据处理、设备维护、加工BOM管理、装配可视化及数据的统计分析.该系统的应用实施将为优化装配流程、改进装配工艺、指导容差分配、提高装配精度和生产效率提供实用的历史资料和技术支持.更多还原

【Abstract】 To implement numeralization,automation and flexibility during the aircraft join assembly,a data management system for a certain type airplane was proposed,which was required in the processes of large-scale postural adjustment,fuselage join and finish machining.Based on a workflow-driven task manager,the system utilized an extendable architecture of multi-ties C/S.The block reading/writing,the parameterized strategy,and the dual-mechanism by online Oracle database and offline XML files were introduced for efficient data storage and retrieval.Simultaneously,several key technologies were particularly illustrated,including status data handling,equipment maintenance,machining BOM disposal,visualized 3D-simulation,data mining and statistical analysis,etc.Application of this system beneficially provides history information and technical support to optimize assembly workflow,improve assembly techniques,redistribute error tolerance,ensure accurate assembly and speed production.更多还原
