In order to analyze the adhesion vibration characteristics of vertically arranged double bundled conductors, the vibration equation of adhesion conductor under the coupling action of aerodynamic force and electromagnetic force is established. Firstly, the electromagnetic force on the conductor with different splitting spacing is simulated by COMSOL software. Then, based on the Runge-Kutta numerical calculation method and the vibration mathematical model, the displacement time history curve and amplitude value of the adhesive wire under different wind speed, span and initial spacing are obtained. Finally, a 220kV laboratory model is built, and the real-time monitoring of the wire vibration data is carried out to verify the accuracy of the mathematical model and simulation results. The results show that the coupling effect of aerodynamic force and electromagnetic force is the main reason for the vibration of the wire. The larger the aerodynamic force and electromagnetic force, the larger the amplitude of the wire.
