Modeling and simulation of thrust reverser hydraulic actuation system based on AMESim
Abstract: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.
Keywords:thrust reverser actuation system  worm gear  screw nut  AMESim model  mechanics characteristics simulation
