Abstract:
Acknowledgments: The investigation that formed the basis for this article was instigated by the author in cooperation with four organizations that participated in
experimental efforts as follows: the leaf spring manufacturer (leaf spring peening and fatigue testing), Electronics Inc. (media inspections), Lambda Research Inc. (residual
stress measurements, metallography and microscopy) and Progressive Technologies (experimental peening trails). The contributions of all involved are highly valued and
appreciated by the author. Additionally, the author acknowledges the combined efforts of Dave Barkley and Kathy Levy, with The Shot Peener magazine, to enhance the figures
and graphs of the article.
INTRODUCTION
This article presents the initial findings from a peening optimization study in which improvements in peening processing and the durability of leaf springs were the ultimate
aims. The project has not been completed, but there are valuable lessons already and these are highlighted in this article.
