Landing gear is an assembly of various sub-systems, namely, gear, axle, hydraulic actuator and accessories and brake system. The landing gear supports the fuselage and have to bear the dead weight of the aircraft under static condition. Nowadays, retractable landing gear system is more commonly used. It is exposed to atmosphere and, hence, wind during landing and takeoff only. As wind is an inconstantly varying natural dynamic phenomenon, due to this the engineers while designing components like landing gear need to take a note of the vibrational characteristic (natural frequency) as it may induce unnecessary vibrations which may lead to irreparable damage and cause tragic failure of the component. In this paper, the modal analysis of landing gear has been carried out to find its natural frequency in MATLAB R2018a using Partial Differential Equation Toolbox and the CAD model of landing gear is created in CREO 3.0 and imported as a binary stereolithography file in MATLAB.
