不同工况条件下矿井提升机主轴的数值模拟研究

Numerical Simulation of Mine Hoist Spindle under Different Working Conditions

对不同工况条件下矿井提升机主轴的变形和应力演变特征进行了数值模拟研究,同时对数值模拟结果进行了现场实测验证,认为游动卷筒外壳位置所受的应力最大,主轴左侧轴承位置所受的应力最大,二者均满足强度要求,中部轴肩位置变形最大,为0.73mm,满足主轴的刚度要求;现场实测结果与数值模拟结果较为接近,从而验证了数值模拟的可靠性。

The characteristics of deformation and stress evolution of shaft of mine hoist under different working conditions are studied by numerical simulation.At the same time,the results of numerical simulation are verified by field measurement.It is concluded that the maximum stress on the shell position of moving drum is caused by the deformation and stress evolution of shaft under different working conditions.The stress on the left bearing position of the spindle is the largest,both of them meet the strength requirements,and the deformation of the middle shoulder position is the largest,which is 0.73 mm,to meet the stiffness requirement of the spindle.The field measurement results are close to the numerical simulation results,so the reliability of the numerical simulation is verified.
