【摘要】：通过有限元分析软件Abaqus、Matlab数据拟合工具及单轴拉伸试验,研究了Yeoh本构模型、Ogden本构模型及伪弹性理论模型对炭黑填充天然橡胶的Mullins效应仿真效果及规律。结果表明,(1)对单轴拉伸主加载曲线的拟合,Ogden模型精度更高,而Yeoh模型随着炭黑含量的增加在小变形处的拟合效果变差;(2)提出了伪弹性参数与伸长比之间的关系,找到了一种快速计算伪弹性参数的方法,且精度良好,极大地提高了计算效率。
[Abstract]:By means of the finite element analysis software Abaqus Matlab data fitting tool and uniaxial tensile test, the simulation effect and regularity of Mullins effect of Yeoh constitutive model and pseudoelastic model on carbon black filled natural rubber were studied. The results show that the accuracy of the Ogden model is higher than that of the Yeoh model with the increase of carbon black content. The relationship between the pseudo-elastic parameters and the elongation ratio is put forward by the Yeoh model with the increase of carbon black content in the small deformation area. A fast method for calculating pseudo-elastic parameters is found, and the accuracy is good, and the calculation efficiency is greatly improved.
