摘　　要：采用有限元模拟与实验相结合的方法,借助有限元分析软件ABAQUS和FE-SAFE平台,结合相关橡胶疲劳实验方法,有效预测了硫化天然橡胶(NR)哑铃型试样的疲劳寿命。结果表明,对于该配方的硫化NR,当橡胶本构方程选用Arruda-Boyce模型时,模拟的橡胶试样单向拉伸力学行为(应力-应变)与实验值比较吻合;通过ABAQUS和FE-SAFE平台模拟得到的硫化NR试样的疲劳寿命与疲劳实验结果相接近,误差在1.98%范围内。验证了有限元软件ABAQUS和FE-SAFE相结合模拟结果的准确性,以及预测橡胶材料疲劳寿命的可行性。This article combined the finite element simulation and experiment,with the aid of finite element analysis software ABAQUS and FE-SAFE.Vulcanized natural rubber dumbbell specimen＇s fatigue life was predicted effectively.Comparison with the experimental results showed that for vulcanized natural rubber,the mechanical behavior of uniaxial tension predicted by the finite element model of dumbbell specimen was consistent with the test result when selected the Arrude-Boyce model.Moreover,the fatigue life of the dumbbell specimen obtained by the FE-SAFE software was close to the experimental result and the error was less than 1.98%,verified that the rubber material fatigue life prediction with two kinds of software was feasible.
