The main goal of this work is to develop a calculation method to determine the fatigue damage at different loading spectra. The methods to calculate the durability are divided into those that are used when there are data on loading in the time domain and those that use data on loading in the frequency one. In this paper, the approaches were studied and refined that allow comparing the durability.
