摘　　要：摩擦提升机主轴装置是一个重型的复杂空间焊接结构,受力状态相当复杂。笔者以JKMD-4.5×4井塔式四绳摩擦式提升机为模型,在分析了其受力状况的基础上,建立起提升机主轴装置的有限元模型;并利用有限元分析软件ANSYS,通过施加边界条件和载荷等步骤,得到该提升机主轴装置的前10阶模态频率及相对应的主振型,以及应力场变形分布情况。A main axle installment is a heavy dimensional structure with complicated welded parts. The structure bears complex load. This paper analyzes the force conditions of the 4-rope winder machine of a JKMD-4.5 × 4 tower and builds a finite element model of the main axle installment. Boundary condition and load was applied to obtain the preceding 10 steps modal frequencies and the corresponding vibration modes including the stress distribution through the ANSYS finite element analysis software. The result is helpful for optimal design of the main axle installment.
