摘要
建立了辊子振动模型和带钢振动模型,得到了保证辊子不发生共振的辊径D。计算了带钢临界运行速度Vmcr,分别分析了Vmcr随带钢长度a、宽度b、厚度h、张力T的变化规律,形成比较完善的极薄带钢高速准备机组振动计算方法。比较原有的经验方法,更加准确、可靠。在机组设计和机组控制上,有效避免共振。
Roll vibration model and strip vibration model are established. The roll diameter which can avoid vi- bration and strip critical running speed is calculated, and the changing rule of strip critical running speed with strip length a, width b, thickness h and tension T is analyzed respectively. The perfect vibration calculation method of high speed preparation line of super thin strip is formed. Compared to the original experience design method, the design results are more accurate and reliable. Vibration is avoided from line design and line control.
