| 摘 要： | 为降低高弹性联轴器疲劳寿命研究成本及缩短其开发周期，基于一型广泛应用的成熟产品，通过FE-SAFE/ABAQUS联合仿真预测其疲劳寿命，并以实际使用寿命来验证疲劳寿命预测的可靠性。首先通过橡胶材料的单轴拉伸、平面拉伸力学试验拟合出能准确描述其力学性能的二次多项式本构模型，计算获得了该产品橡胶块在工作载荷下的应力、应变分布，最后通过疲劳寿命分析，得出了该产品无限寿命的结论，这与其实际使用寿命相符合。表明该疲劳寿命预测方法切实可行，并可用于同类产品的设计、开发。

| Abstract: | In order to reduce the research cost of high elastic couplings'' fatigue life and shorten the deve-lopment cycle, research was carried out on a mature product which had been widely used in the market. Its fatigue life was predicted by FE-SAFE/ABAQUS combined simulation, and the reliability of fatigue life prediction was verified by actual service life. The quadratic polynomial constitutive model which can accurately describe the mechanical properties of rubber material is fitted through uniaxial and plane tensile tests. The stress and strain distribution of the rubber block under working load was calculated and obtained. Finally, the conclusion of the product''s infinite life was obtained through fatigue life analysis, which was consistent with its actual life. The accurate prediction indicates that this fatigue life prediction method is feasible, and can be used in the design and development of similar products. |
