日本語題目 歯付ベルト用コードの引張強度低下 英語題目 Reduction of Tension Strength in Synchronous-Belt Cords 著者名 高橋秀雄,飯塚博,高橋美喜男 掲載情報 日本機械学会論文集 C編 Vol.67 No.656, pp1145-1150, 2001 要旨 Reduction of tensile strength 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 tensile strength was reduced after the bending fatigue. The FEM results showed that the reduction of tensile strength could be explained by the initiation and extension of the de-bonding in the cords. A simplified mechanical model was proposed to explain the reduction of tensile strength of cords. キーワード Mechanical Element, Fatigue, Composite Material, Synchronous Belt, Helical Cord, Strength, FEM Analysis, Mechanical Model 論文集への収録 あり ベルト伝動技術論文集2007
