摘要
针对飞机机翼装配复杂、装配调试周期长等问题,提出了改进A*算法结合位姿矩阵算法的飞机机翼快速建模装配方法.在MBD环境下与装配特征自动识别过程相结合,将装配模型标准化,并利用轮廓识别算法进行特征识别,采用A*算法获取最优装配路径.当正确获得几何特征、装配特征和约束之间的关系时,以改进A*算法-位姿变换算法为内核开发快速建模装配信息显示系统,将所需的功能集成在快速建模装配信息显示系统界面,进行交互式的快速建模,并显示更多的装配信息.对装配过程进行实验验证,与位姿矩阵算法相比提高了机翼翼盒装配的效率和准确性,从而验证了该方法的有效性.
Abstract
To the problems of complex aircraft wing assembly and long assembly and debugging cycle,a fast modeling and as-sembly method of an aircraft wing with improved A*algorithm combined with positional matrix algorithm is proposed.The as-sembly model is standardized in the MBD environment in combination with the automatic assembly feature recognition process,and the contour recognition algorithm is used for feature recognition,and the A*algorithm is used to obtain the optimal assem-bly path.When the relationship between geometric features,assembly features,and constraints is correctly obtained,a fast mod-eling assembly information display system is developed with an improved A*algorithm-position transformation algorithm as the kernel,and the required functions are integrated with the fast modeling assembly information display system interface to perform interactive fast modeling and display more assembly information.The experimental verification of the assembly process improves the efficiency and accuracy of wing box assembly compared to the positional matrix algorithm,thus verifying the effectiveness of the method.
