Research and practice on computer aided ergonomie design system

Aimed at evaluation and revision of cab space design, and based on standard model of the human sitting posture (50th percentile adult male), the paper takes the upper limb movement in human sitting posture as research object, using VC++6.0 and an open graphics program interface technology to realize the design of computer-aided ergonomic system. It's realized the simulation of postures and arm movement control in three-dimensional space, the initial construction of computer-aided ergonomics design system, and the basic framework of cab space evaluation and revision.
