摘要 引入了一种多轴疲劳寿命评估方法,并对该方法的疲劳评估流程进行研究。使用该方法联合热点应力法对国际公开发表的250多个疲劳试验数据进行多轴疲劳寿命预测,验证了该方法多轴疲劳寿命预测的精确度。最后使用该方法成功对自升式平台K型桩腿节点进行了多轴疲劳寿命评估,可为提高桩腿节点疲劳寿命预测的准确性提供有益参考。 A new multiaxial fatigue criterion is introduced.In combination with the hot spot stress method,it is used to estimate the fatigue life of about 250 test specimens published in international open literature,through which the accuracy of the new method is verified.Finally we use the new method to do a successful fatigue life assessment of the pile leg joint.This research provides an available reference to improve the accuracy of the fatigue life prediction of pile leg joint.
