Abstract

The multiple dynamic vibration absorbers systems (MDVA) are widely used to control harmful vibration of the damped system under harmonic excitation. The MDVA have more benefit than the single DVA such as portability and easy to install. This paper using equivalent linearization approach based on weighted dual criterion to obtain explicit formulas of optimal parameters of MDVA for damped primary systems. The numerical studies reveal accuracy of the equivalent linearization approach and optimal formula of MDVA in control vibration of damped primary system.
