Damping of Mechanical Vibrations by Parametric Excitation
The goal of this work is to develop deeper insightinto the method of damping vibrations by means ofparametric excitation in mechanical systems -employing the concept of the so-called parametricanti-resonance. Mechanical systems withsimultaneously varying time-periodic stiffness, damping and inertia coefficients are examined. Atleast two vibration modes are necessary to achievedamping. For these minimum systems a thoroughstability analysis is carried out using ...
