Performance Simulation of Retraction/Extension Mechanism of a Certain Aircraft
摘要
Abstract
To test the performance of the retraction/extension mechanism of a landing gear of a certain aircraft, the mathematic model of the retraction/extension mechanism is presented, and its performance simulation is based on the 3D model of the landing gear and the ID model of the deploying-and-retracting cylinder and the fall-accelerating cylinder. The result shows that this retraction/extension mechanism with theoretical values can fulfill its deploying-and-retracting task during a limited time and that the collision among components of the landing gear is inexistent. Besides, with the help of the co-simulation model, the influence of the structural parameters of the deploying-and-retracting cylinder and fall-accelerating cylinder on the retraction/extension performance is studied, and it is suggested that the cross-section areas of the piston chamber of the deploying-and-retracting cylinder and the piston-rod chamber of the fall-accelerating cylinder are prior selection during the retraction/extension mechanism optimization progress can be as reference of the optimization design.关键词
