Abstract

The method and its implementation is proposed for on-line calculation of
fatigue in structure components of hydraulically actuated heavy
equipment. The method does not use any stress or strain gauges and
relies just on the data about the pressure and position of hydraulic
cylinders. This data is measured in real-time during the machine
operation and is transmitted via internet for processing in the cloud.
The simulation model of the machine (Digital Twin) is used for
simulation of machine motion on the basis of received data. The Digital
twin provides input for 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 the
component. Applicability of the method is tested by comparing its
results with similar simulation verified by experimental measurements.
