Dynamic Response of a Composite Strut of Landing Gear of an Aircraft against Impact Velocity

Abstract

Landing gear strut is one of the critical structural members of an aircraft which sustains impact loads during take-off, taxi and landing phase. So its strength characteristics and dynamic response play an important role in the overall functionality and performance of aircraft. This paper presents the dynamic response of a composite strut of landing gear against different impact velocities. For this purpose, a strut assembly was analyzed using ANSYS LSDYNA software. Velocities were imparted to strut through two lumped masses which represent the total weight of aircraft. The dynamic response of strut was determined in the form of acceleration "g's" at aircraft and a comparison was established among all load cases of impact velocities.
