[en] Expressions for the dynamic matrice elements for Vsub(1-x)Osub(x) (x = 0.17 and 0.03) alloys in the Raphizade model with account for vanadium-vanadium and vanadium-oxygen interaction in two coordination spheres and oxygen-oxygen interaction only of the nearest neighbours. The Vsub(i-x)Osub(x) dispersion curves are calculated for various concentrations of implanted atoms and various constant values of oxygen atom interaction. The applicability of the Raphizade model for describing the lattice dynamics of the disordered Vsub(i-x)Osub(x) solid solutions is analysed and the value of oxygen atom interaction is evaluated
