As to the problem of the dancing of OCS additional wire of high speed railway, this paper analyses the mechanism of the dancing of OCS additional wire in strong wind area and studies the wake wind field at the additional wire and the pattern of the power spectrum varied with wind speed. Through simulation calculation of the wind field and finite element analysis of the additional wire, the dancing of additional wire is recognized as wake galloping and anti-vibration measures are put forward.
