A method study of structural sound fatigue life estimate on the basis of power spectral density

ZHANG JunSHA Yun-dongNI Shao-hua(Aircraft Power and Energy Engineering College,Shenyang Institute of Aeronautical Engineering,Liaoning shenyang 110136)  
This paper introduces two methods of the structural sound fatigue life estimation against the question of the aviation structural sound fatigue failure:Time domain statistical method and power spectrum density method,and uses the latter combining the vibration theory,the strength theory,the Miner linearity cumulative damage theory and the S-N curve relationship and other relative theories,establishes the fatigue life estimation formula of the structure under the narrow band and the broad band random noise loading,which could provide certain reference value for estimating the structural fatigue life in project.
