Dynamic Analysis of Sheet Deformation Using Spring-Mass-Beam Model

Abstract

In the development of sheet-handling machinery, it is important to be able to predict the behavior of the sheets with a high degree of reliability. For automated teller machines and letter sorting machines, in particular, a dynamic analysis of the deformation of each sheet is needed to predict the behavior of the sheets because the sheets are fed and stacked at such a high speed. This paper presents one method of predicting the dynamic behavior of sheets. First, a formula for the dynamic analysis is introduced using a spring-mass-beam model. Then, the calculated results of the sheet deformation due to stacking are presented. These results indicate that the proposed method can predict the dynamic deformation of a sheet.
