Abstract: It is tightly coupled between the simulation task and equipment in traditional distributed virtual maintenance training systems, so the system simulation running is inefficient and difficult to expand. In addition, the simulation resource sharing and maintenance cooperation is also a big problem. In order to solve these problems, the infrastructure and realizing framework of cloud simulation were put forward for the application in weapons virtual maintenance training field. The multilayer infrastructure of Run Time Infrastructure (RTI) component was studied. The key techniques were settled, such as federated members excogitation and transport, simulation process monitoring, simulation visualization and distributed storage. The virtual maintenance system was developed based on cloud simulation technologies, which indicated that cloud simulation was feasible and effective.

摘要： 传统分布式虚拟维修训练系统仿真任务和仿真设备耦合度高，系统仿真效率低，扩展困难；同时，作为分布式交互支撑的高层体系结构(HLA)和运行支撑框架(RTI)仅适用于局域网络，无法实现大范围的仿真资源共享和维修协同互操作。借鉴云计算和云仿真思想，提出了一种应用于装备虚拟维修训练领域的云仿真体系结构和框架实现方案；研究了面向Web服务的广域网RTI组件层次化体系结构，设计了基于Web服务的仿真邦员，实现了仿真过程监控和远程邦员任务迁移功能；基于最小调度法实现了仿真平台的动态负载平衡，研究了平台的可视化仿真功能和仿真数据的分布式存储技术。在此基础上完成了某型装备的虚拟维修训练网络化仿真开发，初步证明了虚拟维修训练云仿真的可行性和有效性
