摘　　要：首先通过对当前港口起重机械结构疲劳寿命分析方法的对比分析,确定出损伤容限法是评估港口起重机械寿命最有效的方法,然后设计出基于断裂力学的损伤容限法寿命评估方案,并给出评估过程中应当注意的事项。By analyzing of several main methods of residual life prediction fo method of life prediction for port Crane is given. Subsequently, this paper d tolerable limit damage analysis based on fracture mechanics, and proposed r port machineries, the most effective esigned a project of life prediction of some cautions during the process ofassessment.
