Method for predicting dynamic loads for a health monitoring system for subway tracks

open access: yesFrontiers in Mechanical Engineering, 2022
This paper presents a method for processing acceleration data registered on a train and determining the health condition of a subway’s substructure. The acceleration data was converted into a dynamic deformation by applying a transfer function defined ...

Investigation of Dynamic Loads in Wind Turbine Drive Trains Due to Grid and Power Converter Faults

open access: yesEnergies, 2021
Electrical faults can lead to transient and dynamic excitations of the electromagnetic generator torque in wind turbines. The fast changes in the generator torque lead to load oscillations and rapid changes in the speed of rotation.
