摘要
Abstract
Taking an ethylene propylene diene monomer(EPDM)rubber shock absorber pad as the re-search object,the initial constitutive model parameters were obtained through a single-cycle tensile test.A constitutive model parameter identification system was constructed with Abaqus as the finite ele-ment solver and Isight as the parameter optimization platform.The Hooke-Jeeves direct search algo-rithm was employed to automatically and iteratively identify the parameters of the Mooney-Rivlin mod-el.The optimization objective was set to minimize the sum of absolute area differences between the ex-perimental and simulated stiffness curves.The results demonstrate that the inversely identified parame-ters characterize the mechanical response of the rubber shock absorber pad under complex boundary conditions more accurately.The errors between the simulated and experimental static stiffness values all fall within±6.7%,which meets practical engineering requirements.关键词
