为了准确的反映板材成形过程中摩擦系数的真实情况,构建板材冲压成形摩擦系数实时测量系统,通过改变凸模圆角半径、凸模拱高和模面曲率半径、拉深筋圆角半径等几何参数,利用有限元软件计算不同模具模面下板材冲压及胀形过程中材料流动的变化情况,得到了材料流动量随各种参数变化的规律曲线,并以此优化设计了板材拉深及胀形模具模面,确定了组合式特征传感器的安装位置,为板材成形摩擦系数实时测量平台的建立提供了指导依据。

In order to reflect the real friction coefficient in the process of forming exactly and develop a real-time measure system of forming,the geometry parameters, such as punch profile radius,the arch rise and radius of curvature,the draw bead profile radius etc.were changed and the displacement in the process of stamping and bulging were analyzed by the finite element software.The curves of the displacement and other parameters were found,by which the punch surface would be optimized and the installed positions of the combined specificity sensor were confirmed.It would be the directive gist for founding the real-time measure system for friction coefficient of sheet metal forming.
