摘要
首先对线性累积损伤理论作了简要说明,介绍了应用累积损伤理论对多向应力时有限寿命的起重机吊钩上端螺纹的疲劳寿命进行了估算,得出了吊钩在有限寿命内其设计是可行的,能够满足使用要求。
First to line accumulation hurt the theories made a synopsis elucidation, introduction application accumulation hurt theories right- ness many to should dint the derrick of limited life span mourn to hook up to carry a thread of tired the life span carried on to estimate, get alourn hook in the limited life span it design is viable, can satisfy usage request.
