中文摘要: |
EPDM橡胶卓越的力学性能是保证其服役设备性能安全的重要保障,但其力学性能受环境温度影响显著。本文以航空用EPDM橡胶材料为研究对象,基于单轴拉伸压缩试验,采用有限元仿真方法研究了20℃~140℃温度对EPDM橡胶力学行为的影响规律。结果表明,随着温度的升高,EPDM橡胶的Mullins效应、扯断力和扯断伸长率等均显著下降。 |
英文摘要: |
The excellent mechanical properties of EPDM rubber are important to ensure the safety of its service equipment. However, its mechanical properties are significantly affected by temperature. In this paper, taking aviation EPDM rubber as an example, the influence of temperature ranges from 20℃ to 140℃ on the mechanical behavior of EPDM rubber is studied based on uniaxial tensile/compression experiment and finite element method (FEM). Results indicate that the Mullins effect, tearing force and tearing elongation of EPDM rubber decrease with the increasement of temperature. |
