摘　　要：磨机衬板截面形貌复杂,且与筒体连接螺栓数目较多,计算过程中往往将衬板按非结构质量处理,这可能导致部分关键位置应力计算出现偏差。基于非线性有限元法,对球磨机有、无衬板2种计算工况进行对比研究,探讨了衬板因素对有限元计算结果的影响。结果表明,衬板模型的加入可以降低球磨机大部分关键位置(如筒体法兰圆角等处)的应力幅值,但筒体内侧焊缝位置的应力幅值则有所增加。The cross-section morphology of the mill liner was complex, and there were many bolts connecting it to the drum. In the calculation process, the liner was often treated as an unstructured mass, which might lead to deviation in the stress calculation of some key positions. Based on the nonlinear finite element method, the two calculation conditions of ball mill with and without liners were compared, and the influence of liners on the finite element calculation results was discussed. The results showed that the addition of the liner model could reduce the stress amplitude at most key positions of the ball mill(such as the flange fillet of the drum), but the stress amplitude at the weld position on the inner side of the drum increased.
