二辊矫直过程工艺参数研究

Study on straightening technological parameters for two-roll straightener production process

应用非线性有限元分析技术,利用ANSYS/LS-DYNA软件动态模拟二辊矫直过程,分析了工艺参数对矫直力和导板力的影响;结合弹塑性矫直理论建立了二辊矫直受力模型;推导出了矫直力的计算公式,计算出的矫直力与实际生产相吻合,可为新型二辊矫直设备的开发和旧设备的改造提供理论依据。

By dynamically simulating the whole process of two-roll straightening based on LS/DYNA module of ANSYS,the influence of different straightening parameters on the straightening force and plate force is analyzed with the nonlinear FEA technique.In combination with the elastoplasticity straightening theory,the forced model of two-roll straightener is established.The calculation formula of straightening force is derived.The straightening force calculated by the formula coincides with that obtained in the practical production.The research results can provide the theoretical basis for the development of new equipment and the modification of old equipment.
