Abstract:Greater demands are being placed on training by development national defense modernization. To cultivate soldiers more conveniently and efficiently, with the lowest consumption to achieve the best training effect, virtual teaching and training system has drawn increasing attention. This article proposes a virtual teaching and training system based on simulation resource pack, which is realized based on the technology structure of resource pack and running platform. And support custom extensions for simulation resource pack. The virtual teaching training system, which integrates teaching, learning, training and testing, meets the training needs of the structure principle, job operation, maintenance and trouble shooting. Application examples indicated that the virtual teaching and training system can effectively meet the teaching needs, save the teaching resources, improve the teaching efficiency, and have achieved good application effect.
