摘　　要：在航空发动机初步设计阶段,将面临发动机产品构型未定、无实物的情况下无法通过实物演示试验的方法给短舱设计活动提供输入的问题。文中采用虚拟维修仿真技术,借助Tecnomatix v12.0仿真软件,通过建立虚拟维修数字样机,模拟运营使用阶段发动机在翼维护和下发/换发2个维修场景下维修人员的维修操作,以确定航空发动机短舱开合的角度,为初步设计阶段的短舱结构设计提供输入。经分析,该型发动机处于在翼维护场景下,风扇罩的开合角度应不小于45°,反推装置的开合角度应不小于34°;该型发动机处于下发/换发场景下,反推装置的开合角度应不小于45°。经与成熟机型的短舱设计对比,结果表明,虚拟维修仿真技术作为动力装置短舱开合角度设计的辅助手段取得了较好的工程效果,不仅能够解决初步阶段短舱设计输入问题,还可以大大缩短设计迭代周期。In the initial stage of aero-engine design,there will be a problem that it is impossible to provide input for nacelle design by means of physical demonstration test when the engine product configuration is not determined and there is no physical object.In this paper,the virtual maintenance simulation technology and the Tecnomatix software were used to establish a virtual maintenance digital prototype and simulate the maintenance operations.Finally,the opening and closing angle of the engine nacelle is determined in the on-wing maintenance and the replacement scenarios of engine.For the engine,the opening and closing angle of the fan cowl should not be less than 45°and the opening and closing angle of the thrust reverser should not be less than 34°in the on-wing maintenance scenario;the opening and closing angle of the thrust reverser should not be less than 45°in the replacement scenario.Compared with the advanced engines,the results show that the virtual maintenance simulation technology has a good effect on the nacelle design.Meanwhile,it can not only provide input for nacelle design in the preliminary stage,but also greatly shorten the time of design.
