Abstract：

Aiming at the problem of poor roll bending quality of integral mesh panel， the impact of different process parameters on the roll bending quality of

integral mesh panel was studied. Taking 2219 aluminum alloy as the research object， the mathematical model of press amount and roll bending radius was established based on the roll bending principle of integral mesh panel， and the error between the predicted and target radiuses is not more than 2.4%. Using ABAQUS software to establish a finite element model， for different friction forces， feeding speed and width-to-thickness ratio of rib, the simulation was conducted. The results show that with the increasing of friction forces and feeding speed， the roll bending quality of integral mesh panel decreases， with the increasing of width-to-thickness ratio of rib， the roll bending quality of integral mesh panel increases. Finally， the finite element model was experimentally verified， and a good fit between the experimental data and the finite element model is obtained， and the error between simulation and experiment is not more than 7.48%.
