线列辊组轧制工艺是一种新的增量式板材轧制工艺，可有效地制造双曲面板材。在这项研究中，设计方程的开发，以预测曲率复杂的曲率成形板形状使用的实验数据。进行了一系列不同曲率的实验。有限元计算结果与设计方程的比较表明，设计方程可有效地用于宽输入曲率范围内双曲板成形工艺的工艺设计。(C)2009年CIRP。
The line array roll set (LARS) rolling process is a new incremental sheet metal rolling process for effective manufacture of doubly curved metal plates. In this study, design equations were developed to predict the curvatures of formed plate shapes with complex curvatures using the experimental data. A series of experiments with various curvatures have been performed. The comparison of the finite element computation results with the design equations has shown that the design equations can be effectively used for process design of forming processes in forming of doubly curved plates over a wide range of input curvatures.
