Dynamic vibration absorber (DVA) with large auxiliary mass has better control performance, but it is also more bulky. Therefore, the mass ratio (the ratio of auxiliary mass of DVA to mass of ...

A typical vibration absorber is a single-DOF spring/mass/dashpot system that is attached to a vibration body. The stiffness and mass of the absorber are designed in order to produce an “anti-resonance ...

The vibration absorbers Russell helped calibrate have been used in commercially available bats since 2010, and so far the response from players and consumers has been very encouraging, he notes.
