摘要：

Aging temperatures play important role in changing the mechanical behavior of rubber, so thermal aging test under different temperatures was carried out to investigate the effect of aging temperatures on the tension, elongation, hardness and fatigue properties of natural rubber. Fatigue life prediction methodology of natural rubber material was proposed by incorporating the finite element analysis and fatigue damage parameter determined from fatigue test. Fatigue life prediction equation effectively represented by a single function using the Green-Lagrange strain and elongation at break. Predicted fatigue lives of the rubber component were in fairly good agreements with the experimental lives within factors of two.
