| 研究三元乙丙橡胶（EPDM）板式支座的性能测试与有限元模型的二次开发。5组EPDM胶料试样经单轴拉伸试验（先进行3次循环加载以消除应力软化效应），测得的拉伸应力-应变曲线均呈现典型的超弹性特征且具有良好一致性。基于Abaqus开发参数化建模程序，利用Python语言进行几何建模、材料属性定义和网格划分的自动化处理，EPDM胶料试样的拉伸应力-应变试验与模拟曲线吻合较好，所建材料的本构模型可准确表征EPDM胶料的非线性力学行为；所建EPDM板式支座的有限元模型及其参数设置准确。本研究为橡胶支座的力学性能模拟研究提供了可靠的参数化建模经验。 |

| The performance test and finite element model secondary development of ethylene propylene diene monomer rubber（EPDM） plate bearing were studied.Five groups of EPDM specimens were subjected to uniaxial tensile tests（three cycles of loading were first carried out to eliminate the stress softening effect），the measured tensile stress-strain curves all exhibited typical hyperelastic characteristics and good consistency.A parametric modeling program was developed based on Abaqus，Python language was used to automate geometric modeling，material property definition and mesh generation.The tensile stress-strain test curves of EPDM compound specimens were in good agreement with the simulated curves，the established constitutive model of the material could accurately characterize the nonlinear mechanical behavior of EPDM compounds，and the established finite element model of EPDM plate bearing and its parameter setting were accurate.This study provided reliable experience of parametric modeling for the simulation research on the mechanical properties of rubber bearings. |
