Abstract

Mechanical properties of rubber material are very important in design procedure to assure the safety and reliability of the rubber components. In this paper, the material test and accelerated heat aging test were carried out. In order to investigate the effects of heat-aging on the material properties, hardness, elongation, stress-strain curves and dynamic characteristics were obtained from various test conditions. Also, rubber material coefficients were determined by both the uniaxical and equi-biaxial tensile tests.

고무부품의 신뢰성을 확보하기 위해서 고무재료의 기계적 물성을 정확히 파악하는 것이 매우 중요하다. 본 연구에서는 천연 및 합성고무에 대해 다양한 환경조건에서 물성시험을 수행하여 경도, 신율 및 응력-변형률 관계와 동 특성을 파악하였다. 또한, 고무부품의 유한요소 해석에 필요한 비선형 재료상수를 단축인장과 이축인장시험을 통해 결정하였다.
