Transient Responses of Repeated Transverse Impacts on Beams

In this paper, the eigenfunction expansion method combined with local contact models are presented to analyze repeated impact behaviors between sphere and beam. The simulations verified experimental results of a simply-supported beam struck 91 times by sphere. order clarify validity solve transverse impacts on beams, simulation spring-mass also compared experiments. It shows that appropriate models, can predict agreeable results, especially (including accumulated permanent indentation, coefficient restitution separation velocity sphere) representing energy dissipations, due consideration structural vibrations, behaviors, as well wave propagations. comparisons model show propagations important for which cannot be neglected in flexible structure impacts. studies analysis response structures.
