Research On The Design Of The UAV Ground Station Console Based On Human Factors Engineering

The Unmanned Aerial Vehicle has become a major research hotspot in various countries.The technology for autonomous control of UAV is becoming more and more mature,thus the mechanical failures are decreasing.However,the proportion of accidents caused by human factors is increasing year by year.As a result,it is particularly important to consider human factors in the design process of the UAV ground station.A good design can provide a comfortable,labor-saving and efficient driving environment for the pilot,as well as safe flight and successful completion of missions for the UAV.Based on the theory of human factors engineering and computer simulation modeling technology,this paper makes an in-depth study on the design of the UAV ground station console.The main contents are as follows:A digital human body model for Chinese pilots is established.The relevant human body size data of Chinese pilots is incorporated and sorted out.The concept of human body multi-rigid kinematics model is introduced.The 5%?50% and 95% of the Chinese pilot digital human body model is established respectively based on the human body size data of Chinese pilots by CATIA Human Builder module and Human Measurements Editor module for subsequent simulation analysis.The main components of the console are designed and modeled.The coordinates of the design eye position were determined in the square cabin coordinate.The design requirements of the visual terminal are summarized by aplication of human factors engineering theory.The human body sitting physiology and sitting posture biomechanics are analyzed,thus the exterior parameter and the adjustment range of the seat is designed.The design and kinetic parameters of the joystick are obtained according to the analysis result of the motion characteristics of hands.The design and kinetic parameters of the pedals are obtained according to the analysis result of the characteristics of the lower limbs motion combined with the recommended mechanical parameters of the pedals.Based on the improved PSO algorithm and Matlab simulation,the layout of each component of the console is designed.The physiology characteristics of the human eye are analyzed.The model which describes the rule of eye position dynamic change is established based on the visual motion characteristics and a new eye position adjustment method in the cockpit is proposed.The visibility requirement is translated into constraint according to the model of eye position dynamic change rule and the monitor layout calculation model is established according to it.The PSO algorithm is improved based on the Logistic model,and proved to be more accurate.The monitor layout calculation model is solved by the improved PSO,thus the layout scheme of the monitor is obtained.The human kinematics linkage model is established based on the human multiple rigid-body kinematics model,and the operational comfort range of the Chinese pilot is simulated through Matlab,thus the layout of the components such as joystick?pedals and others is sovled.The rationality of the layout scheme is verified and analyzed based on CATIA Safe Work model.The visual simulation of the pilot's vision is carried out.The rationality of the layout scheme is verified from the perspective of visual comfort by analyzing the visual effect of the pilot's work.The operational comfort of the pilot's working posture was verified through RULA.The simulation analysis of the two aspects of visual comfort and operational comfort proves the rationality of the layout scheme.
