Abstract
A tuned additive mass to a body subjected to forced vibrations that reduces the vibration amplitudes. The mass is coupled to the body in a manner that establishes a node at the previous maximum response of the body to the applied forces. The mass is constructed to respond in a spring like manner so that vibration frequencies of the mass is tunable to provide counter vibrations in the vibration frequency band. Vibration amplitude reduction is establish by vibrations of the mass that are in phase oppositions of the body.
