COCKPIT GEOMETRY EVALUATION. VOLUME V. VALIDATION
Abstract
A baseline 23-joint variable link length man-model was developed. Three-space movement of the upper torso has been developed utilizing mathematical and computer techniques. Rigorous validation criteria developed held that the model must closely simulate the joint movement paths and the maximum reach envelopes of any sized human operator workstation. Human joint movement data was obtained using a multiple camera technique. Seven seated subjects repeatedly performed movements in an open space and in a multimission flight simulator. A rigorous statistical analysis compared the synthesized arm joint locations of the man-model with those of the subjects. The comparisons were made at joint locations of each task where the greatest discrepancies between the model and the subjects were expected to occur. In general, the results indicated that statistical differences occur; however, practically, they appear negligible. Therefore, the concept of a mathematical man-model appears feasible and future efforts should continue to refine and improve the model as well as the validation criteria and methods.
