Rollers are used widely in the transfer of the steel plate in steel mills. This method causes very loud impact noise because of the deflection of the steel plate and causes noise pollution in the labor environment. In this paper, the relationship between the impact noise and the impact force was examined. Also, a method for reducing the impact force was implemented in order to reduce the impact noise. The noise index was introduced to quantify the relation between impact noise and impact force. Dynamic and impact analyses were carried out using the finite element method. Experiments on impact were also carried out in order to validate the results.
