| 中文摘要: |
| 橡胶制品常在周期性交变应力下使用，橡胶材料的耐疲劳性能决定了橡胶制品的疲劳寿命。从延长橡胶制品的疲劳寿命出发，综述胶料配方、工艺条件和使用环境等对橡胶材料疲劳寿命的影响，总结橡胶材料疲劳寿命的研究方法以及有限元仿真预测橡胶材料疲劳寿命等方面的研究进展，指出橡胶材料传统的疲劳寿命分析方法和耐疲劳性能设计的局限性，这对于提升橡胶材料耐疲劳性能分析与设计及延长疲劳寿命具有指导意义。 |
| 英文摘要: |
| Rubber products are often used under cyclic alternating stress，and the fatigue resistance of rubber materials determines the fatigue life of rubber products. This article reviews the effect of compound formula，process conditions and usage environment on the fatigue life of rubber materials from the perspective of prolonging the fatigue life of rubber products，and summarizes the research progress of rubber material fatigue life research methods and finite element simulation to predict rubber material fatigue life.The limitations of the traditional rubber material fatigue life analysis method and fatigue resistance design are pointed out. This has uiding significance for improving the fatigue resistance analysis and design of rubber materials and extending the fatigue life. |
