Research Of Aircraft Cockpit Interior Layout Design And Ergonomics Method

The cockpit is the main place for pilot control aircraft to perform missions. Ergonomic design of cockpit affects directly the pilot operational efficiency and flight safety. In this thesis, key technologies of ergonomic design for cockpit are deeply studied, and corresponding models and theories are established to support cockpit design.Requirement definition method of cockpit ergonomics design is studied. In order to obtain the complete functions of cockpit human-machine system, the methods of function definition, functional classification and integration are applied to analysis the system functions. Solving sub-function, building features technology matrix, combining and selecting the solving ways for the sub-functions are main methods to get the implementation for cockpit human-machine systems functions. An application instance is used to illustrate the effectiveness of the methods.Cockpit internal general layout ergonomic design method is studied roundly. The boundary range of cockpit space is determined based on eye locus reasoning calculation. Combining with the grey system and the hierarchical clustering theory, the cockpit function area clustering analysis method is put forward. By studying the number of task decisions and performance index factors set, the relationship model of decision-making and performance is established, and provide the basis for aircraft cabin internal general layout design.Cockpit internal equipment layout ergonomic design method is studied. The cabin internal equipment layout knowledge is described by combining with the framework and production representation, and is solved by intelligent reasoning. The intelligent cabin internal equipment layout design method is put forward. Through analyzing comfortable angle range of the pilot upper and lower limbs and smooth of control action, the pilot static and dynamic actions related features are studied. Based on RULA criterion and control comfort analysis, the static and dynamic posture is evaluated, and provide the basis for optimize design of cockpit internal equipment layout.
