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.
The finite element model of Soviet-made 2 × 5 × 2.3 coal mine hoist was established by ANSYS software, and the static analysis of the structure of the wheel was carried out to find out the stress distribution of the wheel under normal conditions. Damaged parts and characteristics of the local structural transformation, and then put forward the effective measures to support the wheel transformation and carried out at the mine site.The results show that: the outer branch of the stress distribution, while the inner branch in the human arc At the same time, a serious stress concentration phenomenon occurred in the cavity. The radius of the humanoid arc can be weakened and the maximum stress of the drum decreased from 299 MPa to 232 MPa, which is reduced by 22 %, Spoke stress is reduced, the stress concentration at the circular arc weakened.
