Wheel hub of an aircraft serves various functions; it allows the aircraft for safely and successfully landing and it equally support aircraft at rest condition. In the past, series of failure had been reported with aircraft as a result of damage to the aircraft wheel hub. This study focuses on the failure analysis and optimization of aircraft wheel hub for optimum landing scenario. LS-DYNA software was used for the analysis. To run the initial static analysis of the hub, the hub model was constrained at the centre. The impact forces act on the wheel from the point of impact and are expected to travel through the entire elements of the tyre. In the first model, 8022N was applied and this was divided among 135 nodes. The nodes are selected to receive direct impact load from the hub. The forces act in the positive y-direction. While for the second model, 4011N is applied and it is divided among 270 nodes. The nodes are selected to be a little closer to the semi line of the hub. Aluminium alloy A356.2 and aluminium alloy 5086-H32 were used for both the initial and final analysis of the aircraft wheel hub. Reduced weight and stresses was achieved by replacing aluminium alloy A356.2 with aluminium alloy 5086-H32 which had a lower mass density (kg/m3), higher tensile strength (MPa) and slightly higher elastic modulus (MPa). The increased in modulus of elasticity helped to increase the rate at which the wheel hub would resist deformation in response to the upward and downward forces acting on the wheel during landing of the aircraft.
