Ergonimic Integration Design Method For Flight Deck

The flight deck of aircraft is the workplace for pilots to get flight information and controlthe aircraft to complete the task. Since human factors are the main causes of the flightaccidents, during flight deck design, it should be considered as the primary factor. As asignificant part, human ergonomics design caused by man-made improper plays an importantrole for the safety of aircraft, the full play of performance, the operational effectiveness and soon. In order to make the pilot completing the driving task safely, efficiently and comfortly,flight deck design should correspond with ergonomics, and then achieve the man-machinematching. Therefore, the flight deck ergonomics design has an important role for theprotection of human performance and flight safety. However, the current aircraft flight deckergonomics design is lacked of intelligent method, and the later evaluation of design is alsoshort of quantitative evaluation index. Based on these, this paper proposed a design method ofergonomic integration of aircraft flight deck. In the conceptual design stage, using fully theknowledge of ergonomics and quantifying ergonomic evaluation can be got. Furthermore, inorder to reflect rapidly people’s will, ergonomics virtual evaluation and design in human loopcan be achieved. Not only does this method shorten the design period, it can also decrease thecost and improve the efficiency. The main contents and creations are as follows:1) The ergonomic research of aircraft flight deck was reviewed. Introducing the aircraftflight deck ergonomic research background was the first step. And then the existing problemswere analyzed after the research progress comparison both at home and abroad. Finally, thepaper research train of thought was determined.2) According to the aircraft flight deck ergonomic problems analyzed in all stages ofdesign, the concept of integrated design of aircraft flight deck was put forward. Meanwhile,the key technologies were analyzed and the design process was given. This is one of the maininvovation points of this dissertation. The key technologies contained a rapid design methodfor flight deck generation by means of achieving ergonomic driving from the flight deckergonomic parameters. Quantify human performance parameters and select these parametersas the goal in flight deck geometric parameters and ergonomic parameters optimization.Based on the virtual reality, much effort was made in order to carry out the aircraft flight deckvirtual ergonomic design in human loop.3) Through the analysis of relationship between the internal flight deck layouts, using theflight deck configuration feature extraction experiments to determine the flight deckgeometric feature parameters is necessary. By related standard access to military specifications, beacons, Society of Automotive Engineers (SAE) International and etc., theflight deck ergonomic parameters and its design knowledge were decided. On this basis, theflight deck ergonomic parameterized template was established. With compromised the flightdeck design knowledge and examples, the flight deck parameterized driving model wasformatted. Based on Caita secondary development, to achieve the flight deck ergonomicinteractive driven design was available.4) Based on the Model of human body above, the common quantitative humanperformance parameters, including visibility, visual comfort, accessibility of manipulation,manipulation, comfort, were researched. With these parameters as the objective functions, theflight deck ergonomic design optimization was studied. This is one of the main invovationpoints of this dissertation.(1) For the visual ergonomics, introducing the response curve was essential todetermining the quantitative solving equations. On the basis of secondary development, thequantitative solving process of visual comfort was established. On the foundation ofSPEOS/CATIA, the virtual flight deck glare quantitative method was formed. Based on digitalcamera and high dynamic image (HDR), real flight deck glare quantitative method was alsoformed too. As a case of windshield glare problem, the flight deck parameter optimizationdesign based on visual ergonomics was studied.(2) On the operation ergonomics, by manipulating positioning experiment, the Fitt’s lawof three-dimensional space in the flight deck environment was studied. And based on reactiontime of the calculation by this law, the accessibility of manipulating the representation of aquantitative method was also determined. Taken joint displacement, relative potential energy,joint comfort and visual comfort performance as the optimization function for human body,the posture prediction optimization method is studied. And then, the established quantitativeevaluation method based on posture prediction control comfort was subsequence. As a casestudy of the central control console problems for setting up the height, the flight deckparameter was optimized.5) The system of human loop flight deck ergonomic virtual design was established. Thisis one of the main invovation points of this dissertation.(1) Build an immersive visual ergonomic evaluation. Firstly, this method adopted SPEOSto simulate flight deck visual. Then introducing the virtual reality glasses Oculus Rift showedthe simulation results and modeling the virtual glasses display color characteristic was toensure that the simulation results and the real result were the same. The next step was toevaluate the immersion human-computer in flight deck visual environment so as to realize real-time visual feedback evaluation results to improve the flight deck design.(2) According to virtual reality glasses, gesture recognition tracking devices, a virtualreality manipulated ergonomic evaluation system by CATIA was set up. Utilizing the OculusRift equipment was to get virtual visual perception and using the MS Kinect device was to getvirtual human driver. All these would achieve flight deck ergonomic design in the human loop,which could have a real-time feedback control evaluation results to improve the flight deckdesign.In comparison with the traditional method, the difference about the method of ergonomicintegration put forward in this paper lies in the combination of the man-machine processdesign. For the traditional design, after the design, it can be improved. This ergonomicintegration design method directly combines the expert knowledge, experience and evaluationto the process of design, which can improve the design efficiency to a great extent. Therefore,the development of ergonomic integration design offers a new developing direction for theflight deck ergonomic design.
