摘要:

为满足机身数字化装配的“一架多型”和“一架多态”深层次柔性需求,使“桥架式”柔性工装具有更好的自主适应能力,必须建立相应的运动学模型,通过在线编程技术合理地规划运动控制策略.针对机身定位形式与柔性工装特点建立了柔性工装运动学模型,研究了基于仿真模型的在线编程原理、装配基准点构建方式和运动控制策略规划技术,提出了结构功能结合工艺需求驱动的仿真环境创建方法.为快速生成运动控制指令,开发了面向机身柔性装配的在线编程系统.以某飞机后机身装配为例,验证了系统的精准性、高效性和超强自主适应能力.

关键词: 机身, 柔性装配, 在线编程, 自主适应, 运动学模型, 仿真

Abstract:

In order to meet the deep flexible demands of “one fixture with more models” and “one fixture with more states” for digital assembly of fuselage, enable the “bridge-frame” flexible tooling to have better capacity for independent adaptability, its kinematic model must be set up and its movement controls strategy must be planned properly by online programming technique. For the locating styles of fuselage and the characteristics of flexible tooling, the kinematic model of flexible tooling was set up, then simulation model-based online programming disciplines, the way of building reference points for assembly and the technology of movement controls strategy planning were studied. The way of building a process-driven simulation environment based on structure function was proposed. In order to generate the codes quickly to control motion, the online programming system for flexible assembly of fuselage was developed. With the assembly of rear fuselage, for example , the accuracy, high efficiency and strong independent adaptability of this system were verified.

Key words: fuselage, flexible assembly, online programming, independent adaptability, kinematic model, simulation
