摘要:

为实现现场工装设备及飞机部件运动路径的动态仿真和实时碰撞干涉预判,提出一种飞机数字化装配系统的运动数据集成及现场监控方法.根据设备运动自由度将数模分解为不同的活动部件,并将设备制造误差和装配误差引入活动部件的装配模型,构建与现场设备及工装装配状态一致的数字化几何装配场景,通过实时读取设备的位置与速度信息实现对现场装配环境的实时重现.利用改进CInDeR干涉检查算法实现对几何模型安全空间干涉情况的实时检查,保证装配过程中飞机与设备的安全.实际应用结果表明该方法的正确性与有效性.

Abstract:

To implement  interference detection and  simulation of the moving trajectory of aircraft components and toolings in the assembly process, a method of motion data integration and monitoring of digital assembly system of aircraft is proposed. Every digital model of the equipments was separated into several components according to its degrees of freedom. And manufacturing errors and assembly errors of the moving components were considered when building the digitized geometry scene of the assembly system so that it is consistent with the actual situation. Then the scene was displayed using real-time data of the equipment positions and velocities. By using an improved CinDeR algorithm, interference between the safety buffers of the geometrical models was detected and avoided. A practical engineering application is provided to verify the correctness and effectiveness of the proposed method.
