DYNAMICS OF VIBROPROTECTIVE SYSTEMS WITH ROLLER DAMPERS OF LOW-FREQUENCY VIBRATIONS

摘要

We study low-frequency vibrations of a vibroprotective system of solid bodies formed by a roller damper and a moving load-carrying body under the action of external harmonic excitations. The dynamic equations of combined motion of the working body of the damper over the hinged roller without sliding and the load-carrying body are deduced and numerically analyzed. A new procedure is proposed for the evaluation of the optimal parameters of adjustment of roller dampers in nonlinear systems.
