Study on Precision of Man-Machine Engineering CAD System and Confidence of Computer Simulation

Data collected from practical measurement of physical model and from computer simulating calculation of digital model are analyzed to evaluate the precision and confidence of simulation system. The results show that CAD techniques and computer simulation can be used quite reliably to manually controlled and operated mechanism systems for human factor analysis in new system design or performance evaluation of an existing system. In such cases, building a physical mockup could be omitted.
