摘　　要：采用ANSYS/LS—DYNA有限元软件模拟计算了中厚板生产中轧机前后辊道在轧件头部平直、头部弯曲、轧件已离开轧机、轧件未离开轧机等不同情况下所受冲击载荷的等效应力,得出在轧件已离开轧机情况下,与辊道发生对心碰撞时辊道所受应力最大;在未抛钢情况下,辊道所受应力远大于前者,且在轧件头部下弯量达60mm时,辊道所受应力已超出其材料许用应力。The equivalent stress of shock load on forward and back mill table were simulated by FEM software ANSYS/LS--DYNA under different conditions, such as piece head straightness and bending, piece throwing off and un--throwing. The maximum value of stress under condition of piece throwing off was obtained. Mean while, the conclusion was put forward that the stree on table is over the allowable value when piece head bending to 60ram.
