摘要： 探索了胶管氯丁胶内胶经热油老化一定时间后应力-应变曲线变化趋势，基于Arrhenius方程预测其高温热油环境下老化一定时间后的一定形变下应力状态，预测结果表明：在高温125 ℃（398 K）热油老化3~5月时，内胶最大应力及最大应变均呈下降趋势。将预测所得应力-应变曲线作为材料参数导入大型非线性有限元软件Abaqus中，计算仿真其静刚度与单元应力状态，仿真计算结果表明：热油老化一定时间后，胶管扣压内胶静刚度减小，使用时间6月时，内胶节点应力达到材料参数最大应力，内胶破损，漏油风险增大。

Abstract: The change trend of stress-strain curve of chloroprene rubber inner rubber after aging in hot oil for a certain time was explored. Based on Arrhenius equation, the stress state was predicted under certain deformation after aging in high temperature hot oil environment for a certain period of time. The prediction results showed that the maximum stress and maximum strain of the inner rubber showed a downward trend at high temperature of 125 ℃ (398 K) for 3—5 months. The stress-strain curve was imported into ABAQUS as a material parameter, and the static stiffness and element stress state were calculated and simulated. The simulation results showed that after a certain time of hot oil aging, the static stiffness of the inner rubber in the rubber hose was reduced, and when it was used for 6 months, the joint stress of the inner rubber reached the maximum stress of the material parameters, and the risk of internal rubber damage and oil leakage increased.
