Analysis on the Stress of Main Shaft of Mine Hoist Based on ANSYS

According to the working process of the mine hoist, describe the load spectrum of the shaft hoist. Use dynamics to analysis the stress of the keyways in various conditions. Through the PRO/E modeling, apply the ANSYS to simulation on the stress of the keyways. Through the transient dynamic, simulation on loading situation in the spindle work. Get the stress figure with time variations and the load of the biggest stress point. Application third strength theory to compare with simulation results, the strength is not reliable in abnormal conditions. Finally, put forward the reason of the broken shaft and corresponding countermeasures.
