Research On The Loading And Design Of Control System For Emergency Logistics Aeronautical Palletized Robot

In emergency logistics transportation,the main modes of transportation are five modes of transportation,such as roads,railways,waterways,aviation and pipelines.Since major disasters often occur in the underdeveloped western regions,where transport networks are sparse in some regions and disasters damage the transport network,the reliability,efficiency,and timeliness of air transport have played an irreplaceable role.Although the time for air transport has been shortened compared to other modes of transport,the way in which materials are assembled and the space utilization rate of aviation container still greatly limits the time and efficiency of air transport.The automatic palletized of aviation container mainly includes the rapid transportation of materials,the loading strategy of materials,the storage and arrangement of materials,and the automatic mesh technology of aviation container.In this paper,through the study of the working process,loading method and moving path of the aeronautical palletized,the movement rules and trajectory of the aeronautical palletized robot are designed.At the same time,the loading model for the emergency logistics aeronautical palletized operation is constructed,which effectively improves the space utilization rate of the aviation container.Firstly,the main functions,performance indexes and loading constraints of aeronautical palletized robot are analyzed.The structural types,driving methods,mechanical structures,gripping devices,and control schemes of aeronautical palletized robot are determined,and the main hardware is selected.Secondly,combined with the characteristics of emergency logistics aeronautical palletized operations,the loading factors of common aviation container were analyzed,and the concept of contact ratio was introduced to deal with the stability of emergency cargo cartons,and the basis for handling loading factors was introduced.On the system load model was constructed.At the same time,combined with the main functions of the aeronautical palletized robot,the system is modularized.Thirdly,the S-shaped acceleration and deceleration movement rules is optimized,and the movement trajectory of aeronautical palletized robot is designed and optimized to shorten its movement time.At the same time,the algorithm of the objective function of the loading model is implemented,and the model is solved based on the improvement of the genetic algorithm.Finally,the performance index and optimization results of the emergency logistics aeronautical palletized robot are verified by experiments.At the same time,combined with the actual situation,the load model and the solution algorithm of this paper are simulated to verify the optimization effect.The final experiment and simulation prove that the emergency logistics aeronautical palletized robot in this study has the advantages of high automation,high efficiency and stability of the system,and can meet the operational requirements of emergency materials.
