本文将相似理论,光弹性方法,Hertz接触理论和数值计算方法结合起来,提出了对轧辊接触应力的一种混合解法,此法不仅可以得到合理的轴向接触压力分布规律,而且也可以得到接触区内的应力场三维解,应用该法对某轧机工作辊进行的接触应力分析,所得结果与轧辊的实际破坏情况吻合,说明本文提出的方法是可靠的。
A composite method of solution for contact stresses on roller was suggested bythe combination of similitude principle, photoelastic method, Hertz's contact theoty andnumerical calculation. Thus, not only the reasonable distribution of axial contact pressureon roller of limited Iength, but also the three-dimensional solution of stress in the contactpost may be obtained. Obeservation on the prachcal damaged roller is in agreement with theresult after contact stress analysis of such a working roller.
