Landing gear failure is a high concern in the aviation industries. As per the Federal Aviation Administration reports, most of the aircraft failures take place at the time of take-off and landing of aircraft. Generally aircraft failures are related to its improper maintenance of landing gear and health monitoring check-ups. In this project work a tri-cycle landing gear shock absorber system model is selected and analyzed it in multi-physics domain, using AMESim software package. AMESim stands for Advanced Modeling Environment for performing Simulation of engineering systems. The software package provides a 1D simulation suite to model and analyze multi-domain intelligent systems, and to predict their multi-disciplinary performance. The various multi-physics domains considered in modeling are mechanical, pneumatic, and hydraulic. Each of the sub-components of these domains are modeled and checked for their output variables. Under the dynamic simulation, vertical loads, strut displacements and efficiency curves of the shock absorber are plotted for various sink velocities. MATLAB programming package is used to perform the mathematical functions to find the efficiency of shock absorber with the help of load and displacement curve plots. In the multi-physics dynamic simulation vertical loads with respect to time and strut displacement with respect to time are plotted. For the validation purpose these plots are tallied with an experimental plots and the plots are well matched. If there is any further iteration is going to conduct on the same model or similar model instead of doing experimental test one can do software analysis to get the results.
