摘　　要：在对球磨机筒体结构进行分析的基础上,通过有限元建模,对筒体进行了模态分析,同时通过试验也表明,基于有限元的球磨机筒体前6阶固有频率与试验得到的球磨机筒体前6阶固有频率比较接近,可以认为球磨机筒体前6阶固有频率就在上述分析数据的附近。Based on the structural analysis of the grinding tube of the ball mill, modal analysis of the grinding tube is carried out by building FEM model. At the same time, it is showed that the natural frequencies of preceding six orders of the grinding tube obtained from FEA is close to the ones obtained from tests, thus, it is considered that the natural frequencies of preceding six orders of the grinding tube near the above analysis data.
