| 摘 要： | 目前国内起重机都是通过每年定期对其重要部位进行检测后,来判断结构的安全状况,这种检测方式具有很大的盲目性,本文通过对起重机工作过程中的应力-时间历程进行分析,计算出其疲劳可靠度指标曲线,并参考起重机结构需要进行检测的最低目标可靠度指标曲线,来判断结构的安全状况并确定结构需要进行检测的时间点,这种基于疲劳可靠性的起重机结构安全检测方法既节约了检测成本,又保证了其能安全有效的运行。

| Abstract: | Nowadays in our country crane structure health status are estimated through monitoring the important crane structure component every year and this monitoring method has much blindness.This paper calculates the fatigue reliability index curve through analysis of crane stress-history course,judges the security of the crane and works out the next monitoring time referred the minimum target reliability index curve which shows crane needed monitoring.This crane structure health monitoring method based on fatigue reliability saves monitoring cost and also insures crane operation safely. |

| Keywords: | fatigue reliability index structure health monitoring accumulated fatigue damage |
