摘要
起重机钢结构在使用若干年后疲劳寿命都有所下降,直接影响起重机的正常使用,需要进行正确的寿命估算.就最常用的三种估算方法进行了分析讨论.
The fatigue life of crane steel structure will inevitably decrease in the course of work, which directly affects the work of crane. Consequently, correct fatigue life evaluation is necessary. Three evaluation ways have been discussed in this paper.
