摘　　要：根据飞机反推力装置液压作动系统的结构特点及工作原理,建立了其蜗轮蜗杆部件、丝杠螺母部件和作动筒的数学模型及系统的AMESim模型。针对某型反推作动系统进行了仿真,分析了其位移、同步性、受力变化规律;通过设置批参数运行的方式,初步分析了丝杠导程角、蜗轮蜗杆减速比和供油压力不足对作动系统性能的影响。仿真结果表明:所建模型能模拟作动系统的伸出和收回时的工作状态,为反推作动系统设计参数选择、受力分析和故障诊断提供了平台。Based on the structure and principle of thrust reverser hydraulic actuator system,the mathematic model and AMESim model of worm gear drive,screw nut drive and actuation system was established through theoretical analyze.Take a kind of actuation system for simulation,the change law of displacement,synchronization,force and the effect of different screw lead angle,worm gear transmission ratio and oil supply pressure to performance was studied.Result showed the model can accurately simulate the working state of the extension and retraction of the actuation system,which provided a platform for the design parameter selection,force analysis and fault diagnosis of the thrust reverser actuation system.
