Abstract
A landing gear suspension system absorbs the vertical energy at the time of touch down as well as when the aircraft is taxiing on uneven road profile, providing traveller and crew comfort with smooth ground ride before take-off, during landing and after landing. This paper explains the study of magneto rheological damper for suspension system of airplanes using PID controller with genetic algorithm. Two different disturbances namely step and random disturbances were given to the simulation model as the road profile. The performance of the simulation model was investigated in term fuselage displacement, velocity and acceleration. The results proved the PID controlled MR damper was better than MR damper and passive system in terms of the fuselage displacement, velocity and acceleration and takes considerably less time to stabilize the aircraft after landing impact happens. It significantly improves the fatigue life of the airplane fuselage and the components inside of landing gear system by reducing the vibration amplitudes.
