| 摘 要： | 本文成功地应用80年代初中期发展起来的随机疲劳理论,结合Cortcn-Dolan修正损伤理论,对桁架式臂架提出一种安全寿命估算方法。通过对现场采样的计算结果与试验验证及工程实践中的统计结果相比较,甚为一致。 |

| Abstract: | Based on the random fatigue theory and the concept of Corten-Dolan culmulate damage. a method of estimation is suggested in this paper for the safety life of the truss-type jibs. The calculative results of the gathered samples from the testing ground quite agree with those of the test in the laboratory and with the statistical data from practice. |
