Analysis and Study of Ergonomics on Virtual Maintenance of Civil Airplane Based on DELMIA

Abstract

By virtual reality technology and ergonomics theory, a basic method of ergonomic analysis on virtual maintenance of civil airplane is herein presented based on DELMIA modeling tool. The method is characterized by two steps: (1) establish the appraisal indexes of ergonomics on virtual maintenance of civil airplane; (2) give a quite complete ergonomic analysis and confirmation system flow chart. By defining maintenance cases and simulating the virtual maintenance process under the DELMIA platform, it is possible to accomplish the ergonomic analysis and evaluation with respect to the ergonomics indexes. The strengths of this method are in its ability to provide the available data and experience for further ergonomic design research and in its broadly applicable 3-D digital human model well suited for computer simulation. Furthermore, because the ergonomic analysis problem in maintainability design is indeed a simulation and confirmation process, the use of simulation techniques and confirmation techniques in this work lends itself to maintainability concurrent design of civil airplane. The ergonomic analysis method is demonstrated using vision analysis as an example.
