Having a highly reliable method to numerically analyze sheet-moving behavior is very important when designing sheet-handling machinery. In this paper, we describe a three-dimensional simulation method we developed that can predict the behavior of sheets in an overlap-type sheet stacking mechanism by means of the finite element code LS-DYNA. The simulation results of the stacking orbit of the sheet head were in good agreement with experimental one. We also analyzed the stacking behavior for 4-folded sheets; and the intervention phenomenon, which also usually occurs in practical stacking processes, was predicted when two or more 4-folded sheets were continuously stacked. We found that this new numerical simulation method is effective for designing sheet-stacking mechanism.
