轮胎胶料超弹性参数研究

在动态剪切模式下对轮胎胶料进行应变扫描，并以此为依据，结合相应的超弹性本构模型对试验数据进行拟合预测。结果表明：Yeoh模型对动态剪切试验数据的拟合效果最佳；三阶Ogden模型对胎面胶动态剪切试验数据拟合效果较四阶Ogden模型好，对胎侧胶和胎圈胶的试验数据拟合结果相近.;The strain scanning of tire compound was carried out under dynamic shear mode，and the experimental data were predicted by combining with the corresponding hyper-elastic constitutive model. The results showed that，the fitting effect of Yeho model on the dynamic shear test data was the best.The fitting effect of three-term Ogden model on the dynamic shear test data of tread compound was better than that of four-term Ogden model，and the fitting effect on the data for the sidewall and bead compound were simila
