摘要
从可靠性理论的基本观点出发,推导出了一个确定构件剩余寿命的数学表达式△t=(ta-ηalnRgz)1/a-t.在此式基础之上,利用声发射技术中某些对构件疲劳损伤较为敏感的特征参数。
Based on reliability theory, an expression has been obtained for determining the remaining service life of a given structure component. It is shown that by employing the acoustic emission technology with the proposed expression, it is able to determine accurately the guaranteed remaining service life of the structure.
