摘要
由于橡胶材料的动态疲劳特性对保证橡胶制品使用时的安全性和可靠性具有重要意义,综述机械载荷、环境和橡胶配方等因素对橡胶材料疲劳寿命的影响,总结用疲劳裂纹萌生寿命法和基于断裂力学的疲劳裂纹扩展法预测橡胶材料动态疲劳寿命方法的优缺点,并展望这2种方法的发展趋势.
Due to the importance of the dynamic fatigue characteristics of rubber materials that ensure the safety and reliability of rubber products in service,the factors that influence the fatigue life of rubber materials are reviewed,such as mechanical load,environment and rubber formulation and so on;The advantages and disadvantages of fatigue crack nucleation approach and crack growth approach based on fracture mechanics are summarized,which are usually used to predict fatigue life for rubber.The current development trends of two analysis approaches are described.
