The Finite Element Analysis for Dimensional Accuracy in Roll Bending of Aluminum-Polymer Laminated Sheet

Abstract:

The padding assisted roll bending technology is the main method to manufacture the cylinder structure with variable thickness. In order to study the deformation behavior of the padding assisted roll bending process, a numerical simulation model of the aluminum-polymer laminated sheet three-roll bending is established based on the finite element method. In the numerical simulation model, the sheet material Al2024-T3 is selected elasto-plastic model, and the padding material nylon PA6-G is elastic model. Based on the simulation results, the following conclusions are drawn: the cylinder radius of the sheet Al2024-T3 decreases with decreasing of the ratio of the nylon PA6-G or increasing of the stroke of the upper roller; And in the direction of bend line, an appropriate thickness compensation of the nylon PA6-G can improve the consistency of the curvature of the sheet Al2024-T3.
