The design of an adaptive tuned vibration absorber

The harmonic vibration of a machine is an undesirable effect of rotating out-of balance mass within the system. It may influence the machine operation by create unwanted noise and resulting excess wear. However the vibration of the machine can be suppressed by attaching vibration absorber whose n...
