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.

Aim: To predict the mechanical product maintenance time is difficult in the situation of lack of physical prototype or similar products’ statistics in stage of design Method: According to the theory of time accumulative estimation method, a product maintenance time prediction method framework based on virtual prototype was constructed, which described the prediction process. The virtual maintenance environment which contains virtual prototype, virtual human and maintenance tools was developed. The virtual human’s position and posture information during the maintenance process was obtained by implementing VBScript language. Result: Basic maintenance motions that constitute the whole maintenance process were classified into 4 categories: body movement, upper limb movement, grasp/replace and operation. Based on MODAPTS (Modular arrangement of predetermined time standard) method and virtual maintenance simulation, corresponding time prediction methods for each categories were proposed. Discussion: Take a maintenance dissassembly and assembly task of engine as an example, through the comparison between the measured actual maintenance time and predicted time of several methods, feasibility and effectiveness of proposed method are verified
