本文列出了计算工作辊道冲击负载的国内常用的公式后,着重介绍了国外常用的动载系数法,并详细介绍了国外有关文献中关于轧件翻钢时动能,轧件表面塑性变形能、传动侧轴承当量静负荷等计算公式,列出了公式推导过程,还结合生产实际进行了一些探讨。文章列举了冲击负载的一些实际测量曲线图表,从而证明了前述各公式推导的理论根据是正确的。本文最后还论述了国内外关于改善工作辊道冲击破坏的一些途径。
This article lists the domestic commonly used formulas for calculating the impact load of work rolls, and emphatically introduces the commonly used dynamic load factor method in foreign countries, and introduces in detail the related knowledge about the kinetic energy, the plastic deformation energy , Equivalent load side of the drive side bearing static load calculation formula lists the formula derivation process, but also with the actual production of a number of discussions. The article lists some actual measurement charts of impact load, which proves that the theoretical basis derived from the above formulas is correct. Finally, this article also discusses some domestic and foreign ways to improve the impact of work roller impact damage.
