Intelligent Planning And Simulation Of Aircraft Wing Assembly Process Route

Assembly is an important part of product production,which is of great significance to improve product quality and reduce production cost.In the wing assembly production,intelligent assembly route planning and assembly simulation can effectively improve the assembly efficiency and find and modify the existing problems.This paper takes the aircraft wing assembly as an example,uses genetic algorithm to calculate the assembly sequence of each assembly unit,uses the expert system to generate the assembly scheme of each process,and then compiles the assembly related documents to simulate the three-dimensional model of the wing,and finally realizes the high-quality and efficient assembly of the aircraft wing.The specific research work is as follows:(1)The evaluation function of wing assembly sequence is summarized.To understand the characteristics of wing structure,collect some wing assembly information and assembly unit information,then summarize the rules in the process of wing assembly,find out the evaluation factors of assembly sequence evaluation,and finally compile the assembly sequence evaluation function.(2)Design of genetic algorithm and expert system.In this paper,the genetic algorithm is used to optimize the wing assembly sequence,code the assembly unit,and then the genetic operator is designed,and the assembly sequence evaluation function is used as the fitness function to complete the genetic algorithm design;the expert system is used to select the assembly scheme for the assembly process,and the relevant expert knowledge is obtained from the technical personnel,and then the assembly rules are put into the knowledge Knowledge base,design a powerful inference engine,complete the design of expert system.(3)The realization of assembly system.It includes the wing assembly sequence optimization subsystem and assembly scheme selection subsystem.MFC and MySQL are used to complete the software development.The interface design of each subsystem is completed,and some auxiliary functions are added according to the requirements.(4)Assembly simulation is used to verify.Before assembly simulation,according to the results of the assembly system,the assembly process route and assembly process procedures are compiled,and then the three-dimensional model of the wing is established and imported into 3dast software to plan the assembly path of each part.The assembly simulation is carried out formally,and the interference check is carried out to verify the feasibility of the assembly sequence.
