Paper Title
Various Modeling Strategies of an Oleo Pneumatic Shock Absorber

This manuscript presents various modeling strategies for an oleo pneumatic shock absorber of an aircraft. The various models included in this manuscript are oleo pneumatic accumulator model, a chamber model, Static four chambers, Dynamic, PID control, metering pin and fault model. The modeling of these models involves multi physics domains like mechanical, thermal, hydraulic and pneumatic sub components using AMESim software. Explained the various sub components of an Oleo-pneumatic shock absorber. Also the modeling and simulation of a shock absorber with leakage as the fault parameter presented. This manuscript also illustrates the computation of efficiency of a shock absorber using MATLAB software. Index Terms - AMESim, Fault modeling, Modeling and Simulation, Oleo-Pneumatic Shock absorber.
