| Abstract: | Shot peening has long been widely used as a low cost and simple method for increasing fatigue strength of the leaf springs. During a survey, it has been found that fretting fatigue failure of semi-elliptical leaf springs in commercial vehicles occur between 3-6 years. Recently, fretting fatigue between leaves has been reduced by careful control of shot peening parameters and with the application of double shot peening. In the present work, the bending fatigue strength of EN45A spring steel parabolic leaf springs is found to be much higher as compared to semi-elliptical leaf springs. The paper discusses the elimination of fretting fatigue between leaves of EN45A spring steel shot peened leaf springs by using taper leaves and rubber pads. |
