摘　　要：针对传统的维修仿真模型不满足虚拟维修环境的要求和缺乏通用性的问题,提出了一种基于关联-层次的飞机复杂机电组件虚拟维修建模方法。该方法将模型分为关联模型(顶层)、层次模型(中间层)和几何模型(底层)。关联模型体现了复杂机电组件与其他组件之间的关联关系,层次模型集成了组件自身的约束、功能、故障、结构等信息,几何模型用于虚拟维修环境中的实时显示和碰撞检测。建立的模型信息表达完整,具有普适性,能够满足虚拟环境对模型的要求,同时可以应用于机务维修训练。最后,通过实例验证了该建模方法的有效性。Aiming at the problems that the traditional maintenance simulation models don’t meet the requirement of virtual maintenance environment and lack generality,this paper proposed a virtual maintenance modeling method of aircraft complex electromechanical components based on association-hierarchy.In this method,the model is divided into the top-level correlation model,the middle-level hierarchy model and the bottom-level geometric model.The correlation model reflects the relationship between complex electromechanical components and other components,the hierarchy model integrates the constraints,functions,faults and structures of itself,and the geometric model is used for real-time display and collision detection in the virtual maintenance environment.The established model information is complete and universal,which can meet the requirements of virtual environment for the model and be applied to the maintenance training of machine.Finally,the effectiveness of this modeling method is verified by the example.
