To effectively suppress the violent galloping of the catenary additional wires in the strong wind section of high-speed railways, the anti-galloping effectiveness and anti-galloping mechanism of the spacer installed on the catenary additional wires are studied. Firstly, the finite element model of the additional wires of the catenary before and after the installation of the spacer is established. Secondly, the random wind field at the additional wires is simulated by the harmonic synthesis method (WAWS). Finally, the galloping response of the additional wires before and after the installation of the spacer is studied by using the finite element software. The results show that the installation of a single spacer at the midpoint of the span can reduce the vertical amplitude of the AF (Additional Feeder) and the PW (Protection Wire) by more than 39.80% and 41.51%, respectively, and the lateral amplitude decreases by more than 16.55% and 38.30%, respectively. The tension of the AF is greatly reduced, while the tension of the PW is slightly increased, so that the galloping of the AF and the PW tends to be synchronized. With the increase in the number of spacers installed, the anti-galloping effect continues to increase. At the same time, the anti-galloping mechanism of the spacer rod to suppress the vibration of the additional wires through the traction effect is clarified, and the effectiveness of the spacer rod in the anti-galloping of the additional wires of the catenary is proved.
