Abstract: Given the criterion of generality and pertinence, virtual training system of military construction machinery is built on the foundation of modular hierarchy. From this point, the main system is proposed, which includes single-soldier training system, collaboration training system, comprehensive evaluation and assistant decision-making. Research content and technique available for the mentioned above are presented. The research provides a technical reference for constructing the support training system. Taking virtual training of certain excavator as the example, process-oriented dynamic evaluation system is presented by introducing time-ordered weighted, the result increases the credibility of the virtual training effect.

Key words: virtual training, support system, effect evaluation, time-ordered weighted

摘要： 以通用性和针对性为准则，采用模块化层次结构分析了军用工程机械虚拟训练体系的基本构架，提出了军用工程机械保障虚拟训练体系应包括完整的单兵作业体系以及在此基础上的协同作业体系、动态评价体系和辅助决策体系。提出了上述保障体系相应的建设内容和技术途径，该研究可为军用工程机械虚拟训练体系构建提供参考。以某型挖掘机保障虚拟训练为例，运用时序加权方法构建面向虚拟训练过程的动态评价体系，增强虚拟训练效果的可信度。
