摘　　要：提出了六辊轧机的支撑辊传动方式对带钢板形影响的问题,分析了主传动轴对辊系的作用力,运用Ansys有限元软件建立了六辊轧机全辊系有限元模型。考虑了主传动轴重量及轧机弹跳,运用所建有限元模型,仿真计算了静态时辊缝控制模式下带钢的板形。计算结果表明位置控制模式下主传动轴重量对带钢板形的影响可以忽略;轧制力控制模式下主传动轴重量对带钢板形的影响是不能忽略的,在实际生产中需要予以重视。The effect of driving ways in six -high roll on flatness is proposed here. The force of transmission shaft on roll system is analyzed. A whole roll system finite element model is built up by using Ansys software. The weight of transmission shaft and the rolling mill bounce are considered in the model. By using the finite element model, strip shape in static state is calculated when in roll gap control mode. The calculation results show that in position control mode the effect of transmission shaft weight on strip shape can be ignored; when in force control mode the effect of transmission shaft weight on strip shape can not be ignored, which should be regarded seriously in practical production.
