Abstract
This paper is dealing with procedures for mathematical modeling of DVA. Usually the problems
of optimization are converted to equivalent single degree of freedom (SDOF) structure at particular mode in order to optimize the damper. There are three main parameters in a DVA system: DVA mass, DVA stiffness coefficient and DVA damping ratio. Consequently, the objective is to find the optimum value of these parameters. This paper is investigating also the effect of relative speed of primary structure and its influence on response.
