摘　　要：为了验证磨机的强度,解决传统计算方法与实际情况出入较大的问题,利用有限元理论,建立磨机回转体的有限元模型,得出空载、破碎介质充填率分别为40%、45%三种工况下磨机回转体的应力应变分布,与实际检测结果进行对比,验证了该计算方法的正确性。To verify the strength of the mill as well as avoid great difference between the strength calculated by traditional methods and actual ones, the finite element model of the mill shell was built, and the stress and strain distribution of the mill shell at no-load mode, 40% and 45% filling ratio of grinding medium were obtained. Through contrast of the simulation results with inspection ones, the calculation method proved correct.
