Life Assessment and Life Extension of an Aircraft Wheel

الملخص EN

The effect of heat treatment and shot peening on the fatigue life of an aluminum aircraft wheel was studied.

The effect of residual stress and heat treatment on the fatigue of specimens was studied by means of fatigue testing, residual stress measurement, and fractography.

Finite element simulation was used for life assessment and evaluation of the effect of surface treatments on the life extension of the aircraft wheel.

The results obtained show that the operational life of the aircraft wheel extended by imposed compressive residual stress and aging treatment.
