摘要
通过疲劳寿命试验，获得了QT60／80塔机钢结构加强部位的疲劳寿命数据，针对此类小样本容量试验的特点，采取了一种效率较高的统计方法，并且获得了该部位的P-S-N曲线，为进一步疲劳寿命评估打下了一定基础。
The fatigue life data or strengthened part of QT60 / 80tower crane structure are obtained in the fatigue test. In accordance with the characteristic of less samples fatigue test, an efficient statistical method is used and the P-S-N curves of this part are obtained,with lays a foundation for the further evaluation of the fatigue life.
