| 摘 要： | 本文推导了随机载荷下的疲劳损伤计算公式。数值计算结果表明：Ｐ．Ｈ．Ｗｉｒｓｃｈｉｎｇ给出的公式在宽带情况下与实际情况不符；Ｇ．Ｃｈａｕｄｈｕｒｙ给出的公式在窄带情况下与实际不符；本文绘出的公式不仅适合于窄带，也适合于具有各种不同带宽的宽带随机载荷。

| Abstract: | In this paper, a formula for fatiogue damage calculation under randorm Loading is presented. It is shown that, in the case of broad band random Loading, the results given by wirsching's formula is not in agree ment whit that given by numerical calculation; in the case of narrow band random Loading,the results given by Chaudhury's formula is not in agreetnent with that given by numerical calculation.However,the formual presented in this paper can be applicable in both broad and narrow band random loading. |
