通过试验得出试件的S-N曲线;利用三维建模软件Solidworks建立模型,并导入ANSYSworkbench中进行疲劳仿真分析;把仿真结果和实验结果进行对比分析,其结果具有较好的一致性。分析结果表明:有限元仿真分析可信度较高,对进一步研究疲劳寿命有一定的借鉴意义。
The S-N curve of the test piece was obtained through experiment. The model was built by Solidworks software and imported into ANSYSworkbench for fatigue simulation analysis. The simulation results and the experimental results were compared and the results showed good consistency. The analysis results show that the finite element simulation is more credible, which is of certain reference significance for the further study of fatigue life.
