Analytical and Experimental Approach of Residual Stress on Deep-Rolled Crankshafts and Auto-Fretted Diesel Injection Rails. Effect on Fatigue Resistances in Service

Abstract:

Article Preview

The fatigue resistance of car components such as crankshafts or diesel injection rails is mainly related to fatigue at geometrical singularities. Its understanding requires the simulations of the different steps of the industrial process resulting in residual stresses generation and their evolutions in service. First concerning crankshaft fatigue damage, a complete analytical model of residual stresses generation and shakedown in fatigue is presented. Then a fatigue criterion is established and validated for this application. Finally, for the high pressure diesel injection rail, this approach can be generalized to the holes intersection singularities.
