Abstract:
      The static and dynamic mechanical properties and compression heat build-up performance of carbon black filled rubber compound were studied by experiment and finite element analysis. The results showed that the compound had obvious stress softening under cyclic loading，and the storage modulus and loss modulus measured by dynamic mechanical analyzer decreased with the increase of temperature.Furthermore，the loss modulus under dynamic compression which caused both stress softening and temperature rise was obtained by the test using a static and dynamic stiffness tester，and the equation of nonlinear compression temperature rise rate was obtained. Finally，the thermo mechanical coupling finite element model was established to fit and analyze the heat build-up and heat transfer in rubber compression process.
