Optimal Configuration and Parameters of Translational Dynamic Vibration Absorbers in Vibroisolation of Mechanical Press

The paper deals with the problem of optimizing the positions and parameters of dynamic vibration absorbers for a mechanical press subjected to polyharmonic inertial excitation. Under the assumption of small vibrations a linear dynamic model of a rigid body performing a planar motion, on viscoelastic supports, with an attached system of translational tuned mass dampers is constructed. The problem of vibroisolation of the machine is presented, considering selected harmonics of the force transmitted to the ground, the solutions with a single DVA are proposed.
