Statics Analysis of Fatigue Crack Propagation of Gear Root Based on Ansys Workbench
摘要
Abstract
As the key parts of transmission components,gear fatigue crack is one of its main failure forms.The stress intensity factor theory of crack tip and Paris formula crack growth theory are adopted to establish the finite element model of tooth root crack growth in combination with Workbench software,and the fatigue life of tooth root crack of spur gear is simulated.The 30° tangent method is used to determine the crack implantation location and the crack growth path is simulated.The results show that the torque has no effect on the expansion path,but has significant impact on life with negative correlation.The location of the initial crack has a significant effect on the propagation path,different locations have different degrees of influence on the life,and the direction of the top of the tooth has the greatest effect.The initial crack depth is negatively related to the propagation path and life,and the influence amplitude is among the three.关键词
