| 摘 要： | 由于橡胶材料具有非线性和大变形特性,使得描述橡胶力学特性的本构模型参数的确定比较烦琐和困难。为了提高橡胶本构模型参数识别的准确性,基于超静定方程求解原理推导出一种新的识别方法。以某橡胶衬套为例,识别的参数应用于有限元分析,对比试验数据,结果表明该识别方法可以准确识别橡胶材料参数,并且精度相对于最小二乘法有了明显改善,显示了超静定识别法的有效性和可靠性。

| Abstract: | Great difficulty exists in the parameter identification of constitutive models of rubber materials because of the nonlinear large deformation characteristics of rubber materials. A new method based on hyperstatic equations was developed in order to improve the accuracy of parameter identification. A rubber bushing was analyzed with finite element (FE) approach, using the parameters identified with the developed method and the least square method. Then the two FE-predicted results were compared with test data. The results reveal that the identification method based on hyperstatic equations can precisely estimate the parameters of rubber material and its accuracy is obviously higher than that of the least square method. The efficiency and reliability of the developed method is validated. |
