Abstract In order to analyze the oscillation characteristics of the adhesive conductor, this paper proposes a oscillation system under the coupling effect of aerodynamic force and electromagnetic force. Firstly, the electromagnetic force varying with the splitting spacing is simulated by COMSOL software. Then, based on the Runge-Kutta numerical calculation method, the displacement time history curve and amplitude value of the adhesive conductor under different wind speed, span and initial spacing are obtained. Finally, based on the analysis of variance and response surface analysis, the amplitude of the adhesive conductor under different combination conditions is analyzed numerically. The analysis results show that the interaction between the initial spacing and wind speed has a significant effect on the adhesive vibration, and the coupling effect of aerodynamic force and electromagnetic force is the main reason for the oscillation of the adhesive conductor; the greater the aerodynamic force and electromagnetic force, the greater the initial energy obtained by the oscillation system and the greater the amplitude of the adhesive conductor.
