The System Modeling And Simulation Of Landing Cear

The Aircraft landing gear is an important part of the aircraft, it shoulders an extremely important mission during take-off and landing of the aircraft. Their work performance and reliability will impact on the use of aircraft and security. Adapt to different environments landing gear design, it not only effectively reduce the aircraft and landing gear during landing by the impact load, enhanced aircraft and landing gear of the anti-fatigue and anti-vibration capabilities, can also increase the passenger comfort.In this thesis,based on the force of the aircraft during landing, it establishes six degrees of mathematical model of the aircraft movement, including the wings and fuselage, landing gear and landing gear includes a buffer pillar and wheel. And it establishes the motion equations of the landing gear based on two–mass- model. The aircraft and the landing gear were linked together by force and motion between them to complete the description of the aircraft landing stste.Based on the modeling of the aircraft and landing gear, it designs simulation program in VC + + environment combined with the use of Vega and OpenGL to display three-dimensional. And it carries off the aircraft landing gear shock experiments to verify the correctness of the model, and it studies the impact load of the aircraft landing gear in the different landing state of motive ship. The pitch and roll of ship will severely affect the impact loadof the aircraft gear. In this paper, in different swing conditionsof ship,it carried out the simulation analysis and gave the results of the simulation analysis. In addition it displayed three-dimensional landing motion of aircraft and two-dimensional chart of gear system, which makes simulation more realistic and more visual.
