Design and implementation of ergonomics evaluation system of 3D airplane cockpit

According to ergonomics factors referred by airplane design department and corresponding standards, structure and function of ergonomics evaluation system of 3D cockpit was designed. Digital human model, based on anthropometry database, comprises 66 segments, 65 joints and 131 degree of freedom. The ergonomics design of man-machine interface can be evaluated in terms of vision, reach and working posture comfort analysis methods and evaluation rules. Interior and exterior visual field of pilot can be achieved with the aid of vision analysis. The comfort of working posture and joints motion can be assessed by reference to joint angles for any selected posture. The details regarding system implementation with technology of OpenGL are discussed at last. The system can be computer-aided too] for airplane designer considering its convenience in using excellent model data interface with other 3D software.
