FE Analysis for Landing Gear of Test Air Craft

Stress analysis plays very important role in finding structural safety and integrity of assemblies. Observed from the literature that majority failures of aircraft structure takes place due to malfunction of landing gear of aircraft system. In the present work, a landing gear is designed by using CAD software and structural safety for static and spectrum loads is analyzed using ANSYS. The maximum possible loads (Mil. Standard) applied through RBE3 connection at the axle end spreading to wheel base. The composite material (Carbon-Hercules AS4) is used to check the strength of the landing gear for self weight, static loads, modal conditions and shock spectrum loads as per mil standards. The results shows lesser stresses and deflections with composite material. (C) 2015 Published by Elsevier Ltd.
