FMS Design And Its Capacity Simulational Evaluation For Typical Aircraft Rotational Parts

Large complex rotary parts of the aircraft are a kind of parts with typical process characteristics.The manufacturing process is complex,the processing cycle is long,and many of the auxiliary tools are needed.FMS(Flexible Manufacturing System)is a modern manufacturing technology and system with the integration of the automation,the computer and the enterprise management technologies.Through the reasonable selection of typical rotary parts family and the comprehensive optimization of its process route,and then using the corresponding flexible manufacturing system to process the parts family,the problems of delivery delay and quality fluctuation of this kind of complex revolving parts can be well solved.Combined with the research and development of arp FMS(aircraft rotating parts’ Flexible Manufacturing System)of the aircraft rotating parts family,this paper analyzes and summarizes the current research status of flexible manufacturing system at home and abroad and its application status in the field of aviation.According to the processing characteristics of three types of typical rotary parts,including outer cylinder,piston rod and rotating shaft,the corresponding production process requirements are analyzed.According to the target production capacity of the arp FMS system determined by the production development needs of the enterprise,the type and quantity of machining equipment required by the arp FMS system are selected and determined,and the detailed process flow and process parameters of various parts are further determined.The characteristics and requirements of flexible quick change tooling in arp FMS system are analyzed,and a general quick clamping method for rotating parts with different sizes is proposed.Based on the comprehensive analysis of the process flow of typical rotating parts,the annular layout scheme of machining equipment in arp FMS system is analyzed and determined.The plant simulation modeling and simulation software is used to model and simulate the arp FMS system,and the processing sequence of the batch part family of the arp FMS system and the dynamic selection of its optional equipment are optimized based on the genetic algorithm,which better realizes the load balance of a variety of equipment,and realizes that the processing cycle of the complete batch workpiece family is shortened from the original 29 days to 24 days,which significantly shortens the theoretical delivery cycle of the aviation rotary part family.Finally,based on the cyclic input of the full set of batches,the annual capacity of the arp FMS system is simulated and evaluated.The simulation results show that the designed arp FMS system can achieve the capacity design goal of the system.
