Abstract
The peening intensity and coverage is simulated by DEFORM® for the conventional shot
peening facilities. Peening facilities are selected by two types; the one is the horizontal-type
and the spring is free to move through the shot tunnel. The other is the turret-type and the
spring is under the compression. Those facilities are conventionally used for the coil spring
industry. Amen® strip is attached in the coil spring to measure the arc height and coverage
under the current peening parameters. Passing the several springs with the strips into the
peening tunnel or turret, the arc height and intensity will be measured and evaluated
whether the peening parameters are adequate for the coil spring quality assurance.
Typically, those facilities are very huge and therefore hard to freely change or optimize the
peeing parameters. Instead, computer analysis model can be a useful and powerful tool. In
this paper, the peening process are modelled and the results are compared with the
measured data to show the validity of the simulation.
