| 中文摘要: |
| 应用Abaqus/CAE有限元分析软件模拟哑铃形橡胶试样在单轴拉伸载荷下的Mises应力和拉格朗日应变分布，提取节点处的数据作为原始数据，导入Matlab二次开发的橡胶疲劳寿命计算程序，得到材料各个节点的疲劳寿命，再利用Python语言将计算结果导回Abaqus/Visualization模块，得到橡胶材料疲劳寿命云图。分析结果与相关试验数据基本相符。 |
| 英文摘要: |
| The Mises stress and Lagrange strain distribution of a dumbbell specimen of rubber material under uniaxial tension loading were simulated by Abaqus/CAE finite element analysis software，and the stress and strain data at every node were extracted and imported to Matlab.The fatigue life of rubber materials at each node was obtained using a secondary development calculation program.The calculation results were imported into Abaqus/Visualization module by using Python language，and then the rubber fatigue life chart was acquired.The analysis results were consistent with the experimental test data. |
