要旨

tensional stiffness in helical cords during bending fatigue was investigated carrying out some experiments, FEM analysis and mechanical analysis. The cords were constructed of stranded glass filaments and Resorcinol-Formalin Latex, and were used in synchronous belts. The stranded glass filaments were de-bonded and the extensional stiffness was reduced after the bending-fatigue. The FEM results showed that the reduction of extensional stiffness could be explained by the initiation and extension of the de-bonding in the cord. A simplified mechanical model was proposed to explain the reduction of extensional stiffness of cords.
