通过疲劳寿命试验，获得了塔机角钢桁架结构节点的疲劳寿命数据，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，并且获得了该节点的Ｐ—Ｓ—Ｎ曲线，为进一步评估疲劳寿命打下了一定基础。
Through the fatigue life test, the fatigue life data of tower crane angle truss structure was obtained. Based on the characteristics of such small sample capacity test, a more efficient statistical method was adopted and the P-S-N Curve, in order to further evaluate the fatigue life has laid a certain foundation.
