本文叙述一种弹性体间有间隙、有摩擦的接触问题有限元解法,该方法通过赫兹问题以及轴和圆盘热套配合问题的验证,其结果和精确解相当一致.应用该方法完成了汽轮机叶根轮缘和大型套装叶轮结构强度设计,并已用于工程实际.
In this paper, a finite element solution to the problem of contact between the elastomer and the gap is presented. The method is verified by the Hertzian problem and the fitting of the shaft and the disk. The result is in good agreement with the exact solution. Blade root flange and large suit impeller structural strength design, and has been used in engineering practice.
