摘要
采用有限元分析方法对轴向循环载荷条件下的螺栓进行了弹塑性的应力应变分析 ,运用多轴疲劳问题的判定准则建立了螺栓疲劳寿命预测模型 。
In this paper, finite element method is used to obtain the details of elastic_plastic stress_strain in the bolts under cyclic axial loading. A reliable model for bolt fatigue life predictions has been established by introducing multiaxial fatigue criteria into the model. Experimental observations are compared with the predicted fatigue lives of bolts.
