摘要
通过材料疲劳寿命方程回归、有限元计算,应用局部应力应变法,预测了螺栓试样疲劳寿命,螺栓试样疲劳试验验证了该方法的适用性及螺栓接触有限元计算结果的精确性。
by means of equation regression on fatigue life-span of materials and finite element calculation, the fatigue life-span of bolt sample was predicted by the partial stress and strain method. The fatigue test of bolt sample verified the applicability of this method and the accuracy of the finite element computational result of bolt contact.
