摘要
以LS-DYNA中的几何模型更新方法对中厚板平面形状控制多道次轧制过程进行了有限元分析,在一道次模拟完成之后,对轧制模型进行几何模型更新,调整辊缝值,修改材料属性、边界条件和载荷,建立下一道次轧制模型并进行数值分析。用此模拟计算的中厚板头尾形状变化规律与实测值吻合较好,证明了几何更新方法可有效地用于分析中厚板平面形状的变化规律,为利用单道次轧制模型求解多道次轧制问题提供了新的方法。
The plate multipass rolling process with plane pattern control was analyzed with updated geometry method on the platform software LS-DYNA. After one pass was finished, simulation model of the next pass was built and the rolling geometry model was updated by changing roll gap, material attribute, boundary conditions and loads. By comparing the simulated results with measured data, it is found that good agreement is achieved, the updated geometry method can be used to analyze the plate plane pattern in plate rolling process and a new method of using simple pass rolling model can be used to solve multipass rolling problems.
