摘　　要：针对厚板轧机在生产过程中,经常发生因钢板翘头撞击导卫而造成钢板头部缺陷,进行了轧机导卫装置有限元仿真计算,对比分析了导卫板和连接螺栓在钢板不同撞击位置、不同撞击角度和不同撞击力大小情况下的有限元计算结果,明确了导卫板和连接螺栓受力状态与撞击位置、角度和撞击力大小之间的对应关系,找到了导卫装置在钢板撞击情况下发生事故的原因和最薄弱区域。During the production process of heavy plate rolling mill, due to steel plate head warping upward and impacting the guide device, some defects were often found on the plate head. The FEM simulation and a- nalysis on the guide device of the roiling mill were finished. Under different impact positions, different impact angle and different impact force, the stress coming from guide plate and the connecting bolts were analyzed and compared. The corresponding relationship between the stress state and impact position, impact angle and impact force of the guide plate and the connecting bolts were c/eared. The causes of the guide plate failure and the wea- kest region under the condition of steel plate impact were found.
