... , the stiffness of the absorber; and c , the damping of the absorber) for the most general case, in which there are N absorbers and M mode shapes, where N and M are any positive integers. A uniform beam to which N vibration absorbers are attached was studied in this analysis. The formulation...

...Mark H. Holdhusen; Kenneth A. Cunefare A state-switched absorber (SSA) is a device that is capable of switching between discrete stiffnesses; thus, it is able to instantaneously switch between resonance frequencies. The state-switched absorber is essentially a passive vibration absorber between...
