Abstract

Grommet is one of the Automotive rubber components and is made from EPDM(Ethylene Propylene Diene monomer M-class) rubber and the nonlinear hyperelastic material properties of rubber are important to predict the behavior of rubber product. In this study, the stable stress-strain relations were obtained from the uni-axial tension test and the equi-biaxial tension test. Finite element analysis for grommet was carried out and heat aging test for the lifetime prediction of grommet was introduced.

그로멧은 자동차의 고무부품들 중의 하나로 에틸렌 프로필렌 고무로 구성되어 있으며, 고무의 비선형 초탄성 성질은 고무제품의 거동을 예측하는데 중요하다. 본 논문에서는, 일축인장시험과 이축인장시험을 통하여 안정된 응력-변형률 관계를 구하고 그로멧에 대한 유한요소해석을 수행하였고, 수명예측을 위한 노화시험을 소개하였다.
