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 mixed method of solution for contact stresses on rollers was suggested by the combina- tion of similitude principle.photoelastic method,Hertz's contact theory and numerical calculation.Thus,not only the distribution regularity of axial contact pressure on roller of limited length,but also the three-dimensional solution of stresses in the contact po- sitions may be obtained.An actual example is presented in the paper.It shows that the practical damaged phenomenon in real roller is in agreement with the result of the analysis
