基于ANSYS的提升机主轴有限元分析

In this paper, a mine hoist shaft is taken for the study,using large CAE software ANSYS to establish finite element model of the spindle, and four kinds of typical working conditions are conducted statics analysis. According to the deformation and stress distribution nephogram of main shaft under these typical working conditions , the paper determined the working conditions in which the shaft appeared the maximum vector displacement sum and von mises stress, and then carried out fatigue intensity check on dangerous cross sections, and put forward three kinds of optimization designs for the spindle. The finite element analysis of the main axis, improves the precision and efficiency of the spindle strength check , and also ensures the reliability of the hoist . The spindle optimization designs provide certain theoretical basis for realizing the rationality of the design of the spindle structure.
