fatigue load life

The prediction of fatigue life is important for steel towers and so on, because for this type of structure wind load is regarded as the main load.

由于风荷载是钢塔架等钢结构的主要荷载，风荷载作用下上述结构的疲劳寿命预估因而是至关重要的。

The probability fatigue life - span of pressure vessel under the action of different cycle load is closely related to the cycle load with high stress.

承受不同循环载荷共同作用的压力容器，其概率疲劳寿命和在高应力水平上的循环载荷有着密切的关系。

Torsional and bending load spectra of drive shaft are worked out and fatigue life of the shaft estimated.
