摘　　要：矿井提升机主轴在外界腐蚀、反复应力等因素影响下容易产生裂纹,降低煤矿生产效率。利用ANSYS对主轴模型进行有限元分析,得到不同工况下的应力应变曲线和J曲线,帮助理解主轴裂纹的扩展规律,加深对其破坏模式的认识。The mine hoist shaft is prone to crack because of corrosion, repeated stress and other factors,which reduces coal production efficiency. Using ANSYS to analyse the model of spindle, obtaining stress-strain curve and the J-curve under different conditions, to help understand the spindle crack propagation law and deepen our understanding of failure modes.
