ABSTRACT
This subject focuses on the simulated shot peening analysis of the collision energy and simulated collision energy distribution on coil spring. The authors studied hit
condition by changing peening angle. There have been no reports that describe an analysis on the simulated shot peening effect on the helical-shaped whereas reports on flat
material exist (Watanabe, 1995) (Fathallah, 1998). In this paper, shot size, peening angle, and spring wire overlapping are considered. The optimum peening angle is computed
in case where a coil spring does not move (but self-rotates along its center axis only), and the collision energy distribution is also calculated in case where the spring
moves about. The effectiveness of this analysis is verified in comparison with the previous test result where light was used to check the shadow of shot shower.
