摘　　要：针对整体网格壁板滚弯成形质量差的问题,研究了不同工艺参数对于整体网格壁板滚弯成形质量的影响。以2219铝合金为研究对象,基于整体网格壁板滚弯成形原理,建立了下压量与滚弯半径的数学模型,其预测半径与目标半径误差不超过2.4%。利用ABAQUS软件建立了有限元模型,针对不同摩擦力、进给速度以及筋宽厚比进行模拟仿真。结果表明:随着摩擦力和进给速度的增加,整体网格壁板滚弯成形质量降低;随着筋宽厚比的增加,整体网格壁板滚弯成形质量提高。最后,对有限元模型进行了实验验证,实验数据与有限元模型拟合度较高,仿真与实验误差不超过7.48%。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%.
