The major role of landing gear is to absorb the impact energy generated by landing of aircraft. The impact energy is absorbed by shock absorber of landing gear and the residual impact energy which is not dissipated by shock absorber cause the ground reaction force. The main purpose of performance analysis of landing gear is to predict the ground reaction forces in landing conditions. In this paper, the equation of motion for 2-DOF oleo-pneumatic shock absorber was established and numerical analysis was done by using MATHCAD. Analysis results were compared with drop test results to verify adequacy of equation.
