摘要
针对虚拟维修在建模与仿真等核心环节的研究中存有很大局限的问题,提出了虚拟维修方法体系,探讨虚拟维修理论与方法,在此基础上开展虚拟维修模型与仿真控制方法的深入研究.提出虚拟维修模型即维修任务网(MTN,Maintenance Task Net),MTN基于Petri网可描述维修过程,可表达维修过程中资源、活动和约束.提出MTN驱动虚拟仿真的触发规则及建立控制虚拟维修仿真机制.通过飞机典型设备维修案例对提出的虚拟维修模型和控制机制进行了实例验证,应用结果验证了建模与仿真方法的有效性,为支持维修性工程应用提供了可行的技术途径.
The theory of virtual maintenance is not fully studied and researches are deficiency in the field of virtual maintenance modeling and simulation.The methodology architecture of virtual maintenance were discussed and built,and virtual maintenance model and simulation control method were studied.The model of virtual maintenance called maintenance task net（MTN） was presented,and MTN based on Petri net can describe maintenance process and the factors including state,action and condition.In addition,the fire rules and the control mechanism of virtual maintenance simulation which is driven by MTN were presented.A case study of the line replaceable unit（LRU） repair of an aircraft was conducted,and the result confirms the validation and feasibility of all the studies,which can become a new technique means for maintainability engineering.
