摘　　要：针对目前小型航空发动机装配车架结构形式单一、空间运转自由度不足等问题,设计了一种新型小型航空发动机装配车架,增加了主支点翻转支撑机构和液压系统升降机构,并引入了负载敏感系统对液压回路进行控制,从而保证了发动机上所有零部件的装、拆、检测等操作均位于最佳工作平面上。仿真表明,新型小型航空发动机装配车架具有机体安装可靠、操作简单和换向平稳等优点,最大限度降低了操作人员的劳动强度,提高了生产效率,保证了发动机的装配质量。In order to solve the problem that the present assembly frames for small aero-engine have been facing the disadvantage of single structure and lacking of freedom,a new assembly frame is developed.The improved assembly frame introduces the main fulcrum to support mechanism and the hydraulic system to lift mechanism,and also introduces the load sensitive system to control the hydraulic circuit,so as to ensure that all parts of the engine assembly and testing are located at the optimal working plane.System simulation shows that the new assembly frame has the advantages of reliable installation,simplifying operation and making change smooth,reducing the labor intensity of operator,improving the production efficiency and ensuring the assembling quality of the engine.
