The present paper deals with the experimental analysis and the numerical modelling of the fatigue performance of gears. Such components, used for the mechanical transmission of a racing car, are made in high strength steel and carburized, quenched, shot-peened and superfinished before exercise. After a brief introduction on the state of the art on fatigue design methods, up to present main results are presented. The influence of shot-peening and of superfinishing on the fatigue limit were studied, then the operative parameters of the peening treatment were optimized, and the whole S-N curve of the peened component was determined. On the basis of DOE statistical methods and of theoretical models, a methodology for fatigue design of highly loaded components was developed.

Abstract

The present paper deals with the experimental analysis and the numerical modelling of the fatigue performance of gears. Such components, used for the mechanical transmission of a racing car, are made in high strength steel and carburized, quenched, shot-peened and superfinished before exercise. After a brief introduction on the state of the art on fatigue design methods, up to present main results are presented. The influence of shot-peening and of superfinishing on the fatigue limit were studied, then the operative parameters of the peening treatment were optimized, and the whole S-N curve of the peened component was determined. On the basis of DOE statistical methods and of theoretical models, a methodology for fatigue design of highly loaded components was developed.
