| 中文摘要: |
| 建立减振型三叉式万向联轴器的简化模型，通过获取橡胶减振元件单轴拉伸和等双轴拉伸试验数据，采用非线性最小二乘法对数据进行拟合而确定材料的本构模型；对减振型三叉式万向联轴器的关键部件橡胶减振元件、滑块主体、滑块约束层和连接盘导向槽进行非线性静力仿真分析。结果表明：在不超出橡胶材料的强度和刚度许用范围时，橡胶减振元件的厚度越大，其对减振型三叉式万向联轴器的减振效果越好。 |
| 英文摘要: |
| A simplified model of vibration-damping three-section universal joint was established，and
the constitutive model of the material was determined by fitting the uniaxial and equibiaxial tensile test data
of the rubber damping element with non-linear least squares method. Nonlinear static simulation analysis was
carried out for the key components of the joint，including rubber damping element，slider body，slider restraint
layer and guide groove of connecting disc. The results showed that，when the allowable range of strength and
stiffness of rubber material were not exceeded，the thicker the rubber vibration-damping elements was，the
better the vibration reduction effect of the vibration-damping universal joint was. |
