【摘要】 为降低飞机虚拟维修过程模型的复杂度，提出一种元模型融合下的虚拟维修过程建模方法。通过分析飞机维修任务，得出不同飞机维修任务中具有相同维修序列这一特点。从维修任务中提取仿真要素，使用SysML状态机定义维修对象元模型，确定元模型融合的约束条件，并提出元模型融合下的虚拟维修过程建模方法，该方法可通过重用符合装配关系的元模型来表达相同的维修序列，进而减少模型节点数量，降低模型复杂度。最后，在A320虚拟维护训练系统中，以发动机接口组件维修任务为例验证了方法的有效性。更多还原

【Abstract】 In order to reduce the complexity of the aircraft virtual maintenance process model,a virtual maintenance process modeling method under meta-model fusion is proposed. First,by analyzing the aircraft maintenance tasks,the feature of having the same maintenance sequence in different aircraft maintenance tasks is derived. Then,the simulation elements are extracted from the maintenance tasks,the maintenance object meta-model is defined using SysML state machine,the constraints of meta-model fusion are determined,and the virtual maintenance process modeling method under meta-model fusion is proposed,which can express the same maintenance sequence by reusing the meta-model conforming to the assembly relationship,and then can reduce the number of model nodes and the complexity of the model. Finally,the effectiveness of the proposed method is verified in the A320virtual maintenance training system with an engine interface component repair task as an example.更多还原
