| 中文摘要: |
| 以WH型橡胶隔振器为研究对象，基于超弹性本构理论，应用Abaqus软件建立橡胶隔振器的有限元模型，计算WH型橡胶隔振器的三向静刚度，并与测试结果进行对比。结果表明：对于WH型橡胶隔振器，横向静刚度的计算应选择单轴拉伸＋等双轴拉伸的应力-应变曲线组合，垂向、纵向静刚度的计算应选择单轴拉伸＋平面拉伸的应力-应变曲线组合；本研究探讨的5种超弹性本构模型中，Mooney-Rivlin模型的计算误差最小，Neo Hooke模型仅在描述剪切变形时精度较高，Ogden模型、Yeoh模型和Van Der Waals模型的计算误差较大。 |

| Taking WH type rubber vibration isolator as the research object，based on the hyperelastic constitutive theory，the finite element model of the rubber vibration isolator was established by using Abaqus software，the three-dimensional static stiffness of WH type rubber vibration isolator was calculated，and compared with the test results.The results showed that for WH type rubber isolators，the combination of stress strain curves of uniaxial tension and equal biaxial tension should be selected for the calculation of transverse static stiffness，and the combination of stress strain curves of uniaxial tension and plane tension should be selected for the calculation of vertical and longitudinal static stiffness.Among the five hyperelastic constitutive models discussed in this study，Mooney-Rivlin model had the smallest calculation error，Neo Hooke model only had higher accuracy in describing shear deformation，and Ogden model，Yeoh model and Van Der Waals model had larger calculation error. |
