| 中文摘要: |
| 根据橡胶材料辨识的数学公式推导，利用MATLAB软件通过最小二乘法拟合建立一种橡胶材料本构模型辨识编程计算方法，并与Abaqus有限元分析软件辨识工具进行对比分析。结果表明，相对Abaqus软件辨识工具，该计算方法使用条件较简单，拟合精度较高，可以满足大多数单轴拉伸试验数据的辨识与仿真需求，证实了利用MATLAB程序进行橡胶材料辨识方法的优越性。 |
| 英文摘要: |
| Based on the derivation of the mathematical formula of rubber material identification，a programming method of rubber material constitutive model identification was established by using the least square fitting method of MATLAB finite element analysis software，and compared with the identification tool of Abaqus software. The results showed that，compared with the identification tool of Abaqus software，the calculation method had a relatively simple use condition and a relatively high fitting accuracy.It could meet the identification and simulation requirements of most uniaxial tensile test data，which proved the superiority of the identification method of rubber materials by using MATLAB program. |
