Finite Element Analysis of Aircraft Landing Gear for Structural and Fatigue Safety

Abstract

Stress analysis is essential for determining the structural integrity and safety of assemblies. The most valuable component of an airplane's structure is the landing gear. Depending on an aircraft's type and size, several landing gear configurations are utilized. It has been noted that the majority of aircraft structural failures are caused by the malfunctioning landing gear. This work's primary focus is on the structural design and analysis of an aircraft's main landing gear that is simple in design, has a high strength-to-weight ratio, and is also inexpensive. In this study, a model of a traditional Boeing 737 nose landing gear component is made in a 3-D modeling program and is taken into consideration for analysis using Ansys software. Nickel chromium-molybdenum (NCM) alloy steel, Aluminum 1030, Titanium alloy, and EN19 structural steel were chosen as the materials for the landing gear components. The design load is computed by comparing the maximum weight taken into account for a load on the landing gear and maintaining the factor of safety constant for all four materials. To locate the stress, deformation, and fatigue failure point in the landing gear and to choose the most suited material for landing gear parts from among four grades of materials, structural and fatigue analyses of four chosen classes of materials are performed.
