Modeling Research on Mechanism of Shock Absorber for Aircraft Landing Gear

Through analysis of dynamic and shock absorber force for support type of landing gear,the two mass model and the kinetic equation of the landing gear were established.Using SIMULINK modules in dynamic simulation software MATLAB to simulate the kinetic equation,the performance simulation curves of shock absorber were gotten.Simulation curve and the actual movement of landing gear were consistent,and simulation performance data of landing gear were also in consistent basically with the experimental data,which showed that the validity of the model and dynamic simulation based on MATLAB software were feasible.The simulation results provide the foundation for further strength analysis of landing gear.
