Vibration simulation method for digital twin transformer iron core

The invention discloses a vibration simulation method for an iron core of a digital twin transformer. According to the method, firstly, a sensor is selected to collect transformer surface vibration original signals at multiple measuring points, denoising processing is conducted through variational mode decomposition, and frequency domain features of the transformer surface vibration signals are extracted based on Fourier transform; and then completing transformer iron core vibration characteristic representation based on a voltage iron core vibration characteristic sensitivity and current iron core vibration characteristic interference degree calculation method considering working condition factors. And finally, establishing a transformer working condition-iron core vibration simulation residual network, and realizing digital twin transformer iron core vibration simulation under different working conditions. According to the vibration simulation method for the digital twin transformer iron core, vibration sim
