| Abstract: |
| 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. |
