Abstract

A non-traditional dynamic vibration absorber (DVA) with ground-support is proposed to minimize the impulse response of a single degree-of-freedom (SDOF) system. The conventional wisdom of suppressing random vibration of a machine is to add a damper to its mounting or to increase the mass of the primary system. We have proved that the proposed DVA with ground-support has better suppression of the impulse response of a single degree-of-freedom system than just using the damper alone or by increasing the mass of the primary system. Design guidelines to the engineer to apply the proposed DVA with ground-support for suppressing the impulse response of a single degree-of-freedom system are provided.
