Abstract

An aircraft’s landing gear system plays a critical role in effectively managing and dissipating kinetic energy generated during the landing impact, as well as mitigating vibrations induced by the aircraft’s passage over irregular runway surfaces. This capability is indispensable for the proper functioning of a well-designed landing system. Among the various types of shock absorber landing gear systems employed in aircraft, the oleo-pneumatic shock absorber stands out as the most prevalent and widely adopted choice. It dissipates the kinetic energy generated by impacts when an aero plane lands quickly while also providing passengers with a comfortable ride when the plane taxis slowly. The purpose of this project is to calculate the stress, displacement, strain, and shear stress of three different nose landing gear designs made of various materials like Ti 6Al-6v-2sn, Ti10Al-2Fe-3V, Alloy steel 4340, Ti7Al4Mo, Ti6Al4V of an aircraft during landing using structural fem. For static and modal analysis, the landing gear was created using CATIA software and loaded into ANSYS. As boundary conditions, the working forces on the nose landing gear were used. Finally, based on the, it was determined which material is appropriate for landing gear. Find the total deformation at various frequencies using static analysis and modal analysis using the stress, displacement, strain, and shear stress data.
