Abstract

The impact of spheres is the fundamental problem in engineering. The effect of impact is characterised by coefficient of restitution. A classical problem of impact or ball bounce can be converted into equivalent mass-spring-damper model. This paper deals with experimental analysis of impact of spheres with aluminium surface. Different methods are studied to determine COR experimentally. Experiments are carried out to find COR for various configurations of experimental parameters. The effect of material of ball and initial release height on COR in low velocity impacts is investigated through experiments. Total time of bounce is calculated through simulation model.
