本文介绍了一种求解支承辊弹性压扁量轴向分布的新方法——有限梁迭合法。依据这一方法,编制了计算程序。计算结果表明,本方法比三维弹性有限元求解法效率高,使用方便、灵活,比解析法更符合实际情况。同对,本文采用压环法测出了压扁量沿轧辊轴向的分布规律,得出了计算值和实测值较为相符的结果。 In this paper, a new method to solve the axial distribution of elastic crush of backup roll - finite element method is introduced. According to this method, a calculation program has been prepared. The calculation results show that this method is more efficient, more flexible, and more practical than the three-dimensional elastic finite element method. In the same way, the distribution law of the amount of crush along the roll axis was measured by the pressure ring method. The calculated results agree well with the measured values.
