中文摘要:
      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,而用3种变形模式能够更好地表征胶料在工作状态时的变形状态。
英文摘要:
      The different deformation modes of uniaxial tension,biaxial tension and plane tension were tested for a certain specification of all-steel radial tire compound.The fitting accuracy of Yeoh,Ogden and Van der Waals constitutive models under different deformation modes was analyzed and compared,and the simulation accuracy of the constitutive models under different deformation modes were compared with those of the same specification tire.The results showed that Yeoh model was more suitable when only uniaxial tension data were available,and the three deformation modes could better characterize the deformation state of the compound in the working state.
