| Abstract: | 152726QT railway rolling bearing model is built in ANSYS,and crack is established on the spot with the greatest force,then the singular unit is manually generated on the tip crack.The contacts are built,the force function is composed and the path is set to do finite element calculation of the respective stress intensity factors for different lengths of cracks at different depths under different stress.At last the effect of crack length and load on stress intensity factor is analyzed. |
