摘　　要：运用ANSYS软件建立苏制2×5×2.3型矿井提升机卷筒有限元模型,进行支轮结构的静力学分析,找出卷筒在正常工况下支轮的应力分布规律.针对支轮开裂损坏的部位及特点,对其进行局部结构改造,进而提出支轮改造的有效措施,并在矿山现场进行了实践.研究结果表明:外侧支轮应力分布均匀,而内侧支轮在人孔圆弧处出现严重的应力集中现象;加大人孔圆弧半径可以削弱圆弧部位的载荷;将轮辐加强成箱形结构后,卷筒的最大应力值由原来的299 MPa降低到232 MPa,降低了22%,轮辐应力有所降低,人孔圆弧处应力集中现象减弱.Applied ANSYS to build finite element model of Russia-made 2 ×5 × 2. 3 hoist drum, and carried out static force analysis. Stress distribution law of branch wheel under normal condition was analyzed. The branch wheel was reformed according to the location and characteristic of damage. The structure reform scheme was applied in mine. Research results indicate that the stress of outboard branch wheel is homogeneous, and the stress of medial branch wheel concentrates on manhole arc. The method that oversize the radius of the manhole arc can weaken this location loading. The wheel rib is to be the box structure, the maximum stress reduces from 299 MPa to 232 MPa, which reduces 22 %. The stress of the wheel rib is reduced and stress concentrates on manhole arc is weakened.
