一种计入缺陷因素影响的起重机剩余工作寿命估算方法

An Estimation Method of the Residual Life of Cranes, Which is Affected by the Factors of Defect

应用断裂力学的理论,考虑在役起重机在使用过程中实际存在的缺陷因素,试探寻了一种对在役起重机计入缺陷因素影响的结构完整性的剩余工作寿命评估的方法,从而使对在役起重机剩余工作寿命的评估工作较目前无缺陷剩余工作寿命理论更为准确和科学。

This paper applied the theory of fracture mechanics, considering the exist defect factors of crane in service, try to explore an estimation method of the residual life of cranes, which is affected by the factors of defect, so that the crane in service remaining life assessment work compared with the currently no remaining work life is more accurate and scientific.
