The Research of Maintainability Analysis Based on Immersive Virtual Maintenance Technology

Maintainability as an intrinsic property should be designed and built into a product during the design phases to ensure service reliability. The virtual human can operate virtual prototype in virtual environment instead of the real person to analysis maintainability. This article introduces a method that use the Cave Automated Virtual Environment (CAVE), motion capture system (PHASESPACE MOTION CAPTURE) and virtual simulation software (DELMIA) to build immersive virtual maintenance simulation system, which not only can help analyze the maintenance data and products' maintainability, but also allows the users operate the virtual product in virtual environment. With the help of the simulation system, we can analyze the comfort of the user's action, and evaluate visibility, reachability and operation space of products for maintainability analysis to provide suggestions for the improvement of physical prototype design. At last, this paper will introduce a case study of this immersive virtual simulation system to implement maintainability analysis.
