摘　　要：为快速测定齿轮的弯曲疲劳极限,采用ansys的APDL语言建立有限元模型进行齿根应力计算机仿真分析,再使用局部应力—应变分析理论,按照累积损伤理论和雨流计数法则,应用ANSYS/FE-SAFE软件对齿根进行弯曲疲劳寿命仿真分析。结果表明仿真获得的弯曲疲劳极限比试验结果高6%,可以满足工程需求。To determine the gear bending fatigue limit rapidly, a finite element model was founded by APDL to analyze the tooth root bending stress through computer simulation. Simulation analysis of the tooth root bending fatigue life was analyzed by ANSYS/FE-SAFE software, according to the local stress-strain analysis theory, cumulative damage theory and rainflow counting rule. The results show that the bending fatigue limit obtained by simulation is 6% higher than the test results, which can meet the project needs.
