Improved A*Agorithm Path Planning for Fast Modeling of Wing
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.
