Transformer iron core winding coupling vibration model establishment method, medium and system

The invention provides a transformer iron core winding coupling vibration model establishment method, medium and system, and belongs to the technical field of transformer iron core winding coupling vibration models.The method comprises the steps that signals collected by M optical fiber acceleration sensors arranged on a transformer iron core are obtained and recorded as a first acceleration signal set; synchronously acquiring signals acquired by N optical fiber acceleration sensors arranged on a transformer winding, and recording the signals as a second acceleration signal set; after preprocessing, converting the signals into vibration signals to obtain a first vibration signal set and a second vibration signal set; a frequency domain characteristic of each signal; any one first vibration signal is used as a basic signal, each second vibration signal is filtered, and a filtering ratio is calculated; and establishing a regression model for calculating the influence degree of iron core vibration on winding vib
