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.
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 largescale 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.
