| 摘 要： | 选取某规格全钢子午线轮胎胶料分别进行单轴拉伸、等双轴拉伸和平面拉伸不同变形模式测试,分析比较不同变形模式组合时Yeoh,Ogden和Van der Waals等本构模型的拟合精度,并以同规格轮胎为例对比不同变形模式下本构模型的仿真精度。结果表明,当仅有单轴拉伸数据时适宜选择Yeoh模型,而3种变形模式结合使用能够更好地表征胶料在工作状态时的变形状态。

| Abstract: | The tensile properties of the tire compounds of a selected all-steel radial tire were tested under different deformation modes:uniaxial tension,equi-biaxial tension and plane tension.The fitting accuracy and simulation accuracy of Yeoh,Ogden and Van der Waals constitutive models under different deformation modes were analyzed and compared.The results showed that Yeoh model was more suitable when only uniaxial tension data were available,and combination of all three deformation modes could better characterize the deformation state of the compound in the working state. |
