On the Identification Technology for the Random Load Spectrums [PDF]

open access: yesAdvances in Engineering Research, 2015
This paper deduces the relationship between the frequency response and loads for a structure within the frequency domain, and puts forward a new method for identifying the random loads spectrum. Firstly, the response power spectrum of structural control points is calculated based on the white noise loads spectrum. Then in order to get the corresponding

A Review of the Extrapolation Method in Load Spectrum Compiling

open access: yesStrojniški vestnik - Journal of Mechanical Engineering, 2016
Load spectrum is the basis of fatigue analysis and life prediction in engineering, and load extrapolation is an essential procedure in determining a long-term load spectrum from a short-term one. Selecting a proper extrapolation method is of great significance when considering various forms and characteristics of load.
