Desktop virtual maintenance training system for construction machinery

By analyzing different application objectives and demands on virtual reality technology for design- and training-oriented tasks, the characteristics and requirements of maintenance training tasks are first attained. Based on the desktop virtual reality technology, the functional modules of virtual mainte- nance training system are then designed. Next, the interactive control principles of desktop virtual tech- nology are introduced. Finally, the design concept and technological implementation are summarized on such main functional modules as assembly and disassembly training, fault diagnosis training and training examination and assessment. To this end, a virtual maintenance training system for a specific loader is de- veloped to verify the effectiveness of the proposed method.
