Finite element analysis of a passenger aircraft landing gear for structural and fatigue safety

Landing gear is the most valued element in an airplane framework and it was also noted from a survey that an airplane structure failure occurs because of fracture in its landing gear. In the present study, a prototype of a classic nose landing gear of a Boeing 737 is created in a 3-D modelling tool, and is considered for analysis using an analysing software, the materials selected for landing gear are Aluminium 7075, Titanium 6Al-4 V, and Alloy Steel 4340. The design load is calculated by keeping Factor of Safety constant for all three materials, while comparing the results from analysis performed, the maximum weight is considered for load on landing gear, and then it is analysed for Stress, Deformation, and Fatigue analysis is performed to find failure point in the landing gear.
