Development of a virtual maintenance system for complex mechanical product

Abstract

In order to improve the maintenance training effect of complex mechanical product, a virtual maintenance system was developed. The system framework was proposed, and the main functional modules were elaborated. A multilevel information representation model for complex mechanical product was put forward, and the flowchart of model transformation technology was designed. Moreover, a collision detection method based on hierarchical bounding volume was proposed, and the maintainability analysis and evaluation solution based on maintenance knowledge was presented. Finally, a prototype system was developed, and the proposed system was proved to be efficient through an example of hydraulic winch. © 2013 Xin-hua Liu et al.
