  • In order to study the kinematics and dynamics characteristics of cascade type thrust reverser, the mechanism was simplified and the kinematics and dynamics mathematical model of thrust reverser was established according to the motion principle. Taking displacement of translating sleeve and pneumatic load of blocker door as the input, the displacement, velocity and force characteristic of thrust reverser were simulated, and the trajectory of feature points and the thrust everser load force under different size parameters were comparatively analyzed. The results showed that: the kinematics and dynamics simulation results were in conformity with the real working process. When the mechanism parameters of thrustreverser were selected unreasonably, the interference phenomenon occurred between components.The change of components parameters had a remarkable influence on the maximum load force; when the length of the AC segment of blocker door increased by 6% and the CB segment decreased by 9%, the positive maximum load force increased by 19.53% and the negative maximum load force increased by 12.67%. The model and research results can provide a reference for the kinematics and dynamics analysis and optimization design of the thrust reverser tructure.
