With the continuous growth of global demand for renewable energy,wind energy as a clean and sustainable form of energy has received increasing attention.At the same time,the rapid growth of the domestic economy has also driven the development of the wind power generation industry.Driven by policy support,technological progress,and market demand,China’s wind power industry has achieved rapid development and become one of the world’s largest wind power installation countries.As an essential component of wind turbines,the demand for wind power brakes in the market is also increasing.At the same time,wind power brakes are relatively simple in structure and diverse in types,making them suitable for using automated mixed flow flexible production lines.However,due to the lack of reasonable design for automated mixed flow flexible assembly production lines,assembly line design solutions cannot meet the needs of enterprises.Therefore,starting from the actual situation of wind power brake assembly production process and the relevant needs of enterprises,this article aims to design a mixed flow assembly line suitable for the production of multiple types of wind power brakes,and develop a flexible manufacturing system for wind power brake mixed flow assembly.The system mainly includes the overall scheme design of the wind power brake mixer assembly production line,simulation optimization research on the balance and sorting of the mixer assembly line,collaborative optimization of material distribution and batching area layout for the mixer assembly line,development of the integrated system for the wind power brake mixer assembly line.The specific research work is as follows:(1)Based on the overall analysis of the process flow,enterprise requirements,and production status of wind power brakes,a comprehensive plan for the wind power brake hybrid assembly production line was constructed based on the plan design and structural optimization of the wind power brake automatic assembly production line.The flexible structure design of the wind power brake automatic assembly line was determined Design the simulation scheme for the batching area system of the wind brake mixed flow assembly line and establish an integrated simulation model for the batching area and the wind brake mixed flow assembly production line,ultimately forming a wind brake mixed flow assembly production line that can meet the needs of multiple types of mixed flow assembly.(2)Based on the mixed flow assembly production line model of wind power brakes,a simulation model of the mixed flow assembly production line of wind power brakes is established in the discrete simulation software Plant Simulation.Aiming at the balance and sorting problem of the mixed flow assembly line of wind power brakes,a multi-objective optimization model is established with the goal of minimizing the maximum completion time and the minimum chemical potential load index,taking into account the mutual influence of balance and sorting of the mixed flow assembly line,Propose hybrid parallel encoding,as well as multiple group strategies,adaptive step sizes,elite retention strategies,to form an improved fruit fly algorithm,which achieves the solution of mixed flow assembly line balance and sorting problems in a simulation environment.The simulation results show that the combination of discrete simulation software and optimization algorithms can effectively solve mixed flow assembly line balance and sorting problems.(3)Based on the above research,taking into account the impact of material layout in the wind power brake batching area and material distribution path planning of the batching trolley on the mixed flow assembly line,a mathematical model for the shortest driving distance of the batching trolley is established,and a segmented optimization strategy is proposed.The hybrid optimization algorithm of improved ant colony algorithm and genetic algorithm is used for hierarchical solution,The simulation results show that considering the material layout of the batching area in the mixed flow assembly line material distribution can make the material layout of the batching area more reasonable,further shorten the driving distance of the batching car,and make a comparison of model schemes to verify the effectiveness and feasibility of the algorithm.(4)On the basis of research on the mixed flow assembly production line of wind power brakes,a mixed flow assembly production system for wind power brakes was developed.The interactive interface design in the discrete simulation software Plant Simulation and system integration were implemented on the Visual Studio platform.The functions of each module were introduced in detail with practical examples.
