| Abstract:To improve the performance of suction-tape feeding, the simulation analyses of paper’s mechanical behavior in suction-tape feeding technology was conducted. Considering the geometric nonlinearity of flexible thin paper’s buckling, this article proposed the explicit dynamic numerical analysis method of the paper’s mechanical behavior in suction-tape feeding technology, established the paper’s finite element model based on the shell element of LS-DYNA. The article discussed the stress distribution, deformation law and the performance to resist the side lay’s drawing force of the papers with different stiffness. Results showed that with the increase of paper stiffness, both the paper stress and the ridgy deformation was decreased during vacuum suction, while the ability of resisting the side lay’s drawing force was enhanced. |
