The landing gear is one of the most complicated system of the aircraft, comprising of structural members, hydraulics, energy absorption components, brakes, wheels and tires.It is a unique sub system of an undercarriage in an aircraft which is actuated to land the airframe without any damage. One of the critical parts of landing gear is oleo strut or shock strut.A type of hydro-pneumatic (oil and air) component in an aircraft landing gear system that absorbs the landing shock. In the current investigation, an attempt is made to conduct a static structural analysis by establishing design data of an aircraft landing gear oleo strut and analyse its dynamic characteristics and fatigue life using Ansys 14.5. The computed results are validated for different materials and endurance limit. It is found that Al-7178(Aluminium) has maximum number of life cycles for an applied load condition when compared to Ti-6Al-4V and Al-7178(Aluminium) has high factor of safety.
