The method and its implementation are proposed that allow estimating the
fatigue life of mechanical structure of hydraulically actuated mobile
working machines. The method does not use stress or strain gauges and
relies just on the data about the pressure and position of hydraulic
cylinders actuating the machine components. These data are measured in
real-time during the machine operation and are transmitted via the
internet for the processing in the cloud. The simulation model of the
machine (Digital Twin) is used for the simulation of machine dynamics on
the basis of received data. The Digital twin provides input for the
finite-element analysis of machine's components in order to calculate
the stress history of each component. The results of these calculations
are used for fatigue life estimation of each component. Applicability of
the method is tested by comparing its results with the similar
simulation verified by experimental measurements.
