摘要:
虚拟仿真实验作为物理实验的有效补充,在专业教育过程中起着非常重要的作用。气动锤铆是飞机装配的主要连接工艺之一,开展气动锤铆物理实验具有场地需求大、实验材料价格高、技能水平要求高、干涉量测量复杂等问题。采用信息化手段开展虚拟仿真实验,通过三维虚拟仿真的形式,将大型飞机铝合金构件的锤铆连接过程真实展现在学生面前,使学生在大型飞机虚拟装配环境中进行锤铆工艺系统软硬件搭建、锤铆工艺参数选择、锤铆工艺装备选择和铆接接头质量检测等仿真实验操作和理论学习,帮助学生架构面向高端复杂产品智能制造的机械设计制造及其自动化专业知识体系架构。Virtual simulation experiment, as an effective supplement to physical experiments, plays a very important role in professional education. Pneumatic percussive riveting is one of the main connection processes in aircraft assembly. Conducting physical experiments on pneumatic percussive riveting has issues such as high site requirements, high material prices, high skill requirements, and complex interference measurement. Using information technology to conduct virtual simulation experiments, the percussiveriveting process of large aircraft aluminum alloy components is realistically presented to students in the form of 3D virtual simulation. This enables students to conduct simulation experiments and theoretical learning in the virtual assembly environment of large aircraft, such as software and hardware construction of percussiveriveting systems, selection of riveting parameters, selection of riveting equipment, and quality inspection of riveted joints. It helps students construct a professional knowledge system architecture for mechanical design, manufacturing, and automation for intelligent manufacturing of complex products.
