| 摘 要： | 利用ANSYS/LS-DYNA有限元分析软件,建立了平轧辊系一体化的三维弹塑性有限元模型;利用小型重启动方法对水平辊多道次连续可逆轧制过程进行了模拟计算,分析了不同轧制规程下轧制出相同厚度中间坯的宽展变化以及不同规格的带钢轧制出不同厚度中间坯的宽展变化.不同轧制规程的模拟结果表明,轧制规程对中间坯的宽度变化关系不大,但是不同的轧制规程消耗的能量不同,所产生的轧制力和轧制力矩也不同.利用小型重启动既可以保证轧制过程的连续性,又可避免模型更新法重复建模的复杂性.

| Abstract: | A three-dimensional elastic-plastic finite element model(FEM) of horizontal rolling integration was established with ANSYS/LS-DYNA analysis software.The process of multi-pass and continuous reversing horizontal rolling was simulated by a small-scale restart method.The changes in width spread of equal-thickness intermediate slabs while adopting different rolling schedules and of different thickness intermediate slabs while rolling various strip specifications were analyzed by the model.Simulation results of ... |
