【摘要】：在我国大型民用飞机的检修工作过程中,地面移动式飞机修理坞已是节约成本、节约时间、安全、方便的主要施工检修设备。厦门太古飞机工程公司在大型民用飞机检修中使用的移动式飞机垂直尾翼修理坞(MTE)是目前国内唯一一台大型民用飞机垂直尾翼检修设备,移动式飞机垂直尾翼修理坞通过与标准机库对接,利用机库中标准机位间的空隙,形成一个封闭的飞机垂直尾翼专用修理坞,可以大大提高飞机机库的利用率,广泛用于各种大型民用飞机垂直尾翼的修理工作,设计制造对接式飞机修理坞(不占标准机库空间、移动灵活、平台稳定可靠)以及设计新颖并为用户节省一半以上投资的水平尾翼大平台(兼做修理平台)。因此对这个设备各个部分的模拟分析研究就相当重要。移动修理坞整体钢结构、液压支腿、行走系统是移动修理坞的主要组成部分,其结构性能对整个系统的安全性和经济性有着重要的影响,同时移动修理坞整体钢结构、液压支腿是保证飞机整体安全和不受损坏的关键部件。如果不能准确计算修理坞各组成部分结构的强度、刚度,将对飞机维修时的安全和施工安全有致命影响。本文将修理坞行走驱动系统、网架结构做分析研究,并利用大型三维设计软件SolidWorks和ANSYS对修理坞的主要支撑部件液压支腿和桁架结构进行设计和静力学分析,并将计算结果与材料的屈服强度进行对比,以验证其设计的可靠性、经济性。
[Abstract]:During the maintenance of large scale civil aircraft in China, the ground mobile aircraft repair dock is the main maintenance equipment which can save cost, save time, safety and convenience. The mobile aircraft vertical tail repair dock (MTE), which is used by Xiamen Swire aircraft Engineering Company in the overhaul of large civil aircraft, is currently the only large civil aircraft vertical tail wing maintenance equipment in China. By docking with the standard hangar, the mobile aircraft vertical tail repair dock forms a closed special repair dock for the vertical tail wing of the aircraft by using the space between the standard positions in the hangar, which can greatly improve the utilization ratio of the aircraft hangar. Widely used in the repair of vertical rear wing of various large civil aircraft, design and manufacture docking aircraft repair dock (do not occupy the standard hangar space, flexible movement, The platform is stable and reliable, as well as a large horizontal tail platform with novel design and saving more than half of the user's investment. Therefore, it is very important to study the simulation and analysis of each part of this equipment. The whole steel structure, hydraulic supporting leg and walking system of mobile repair dock are the main components of the mobile repair dock. Its structural performance has an important influence on the safety and economy of the whole system, and the whole steel structure of the mobile repair dock at the same time. Hydraulic leg is the key component to ensure the overall safety and protection of aircraft. If the strength and stiffness of the components of the repair dock can not be calculated accurately, it will have a fatal effect on the safety and construction safety of the aircraft during maintenance. In this paper, the driving system and truss structure of the repair dock are analyzed, and the hydraulic supporting legs and truss structures of the main supporting parts of the repair dock are designed and statically analyzed by using the large-scale three-dimensional design software SolidWorks and ANSYS. The calculated results are compared with the yield strength of the material to verify the reliability and economy of the design.
