Abstract:
      A new kind of ethylene propylene diene rubber（EPDM） laminated bearing was designed and prepared in according to the standard of laminated bearing for highway bridge（JT/T 4—2019）．The elastic modulus and mechanical property of this new bearing under the harshest conditions were studied by experimental and numerical simulation methods．The results showed that the elastic modulus of EPDM laminated bearing met the requirements of the standard．Meanwhile，under the harshest testing conditions， there was no disconnection between the rubber layer and the steel plate layer，which met the engineering design requirements．
