This article presents the design of an electromagnetic pipeline descaling system with an excitation coil structure.The number of turns and radius of the coil are determined through the analysis of the coil's impedance and magnetic field.The frequency of the excitation coil is determined through frequency sweep.A pipeline model is constructed using COMSOL simulation software,and experiments are conducted to measure the impact of the excitation coil on pipeline vibration.The system achieves the effect of pipeline descaling through the shearing action of vibration generated by magnetostriction within the alternating magnetic field.
