ABSTRACT:
A mechanical device is tuned using a tunable damping rod. The tunable damping rod can have its tension increased between its respective engines, to in order to increase the resonant frequency of the mechanical device. Different aspects may also be included; the mechanical device may include a constrained layer damping material, which constraints certain mechanical vibrations. The tuning may tuned the mechanical device to reach that vibration.
