Method for calculating the fatigue life of the structural system of the wheeled machine with random stationary oscillations

摘要

We examine the methodological questions of the calculation of the fatigue life of the elements of the structural system of the wheeled machine (for the example of a trolleybus) with the use of the spectral method of statistical dynamics and random function theory, the corrected fatigue damage accumulation hypothesis, and a new method for schematizing the random loading processes - the method of equivalent cycles. The results of the study can be used in the calculations and tests of the structural systems of the transport machines.
