| Abstract: | A new method of obtaining equivalent load spectrums is presented. The load curves are diveded into infinitesimal sections and the equation of S-N curve is introduced. Furthermore, the integration is performed to get the equivalent load spectrum. The method is more reasonable and more convenient in comparison with other engineering methods. It can be used to equivalent calculations of other load spectrums, too. |

| Keywords: | aircraft load spectrums equivalent calculation integral method. |
