Damper

摘要

An illustrative embodiment of a damper for use with rotary machinery may include a damper mass connected to an electronics housing via one or more piezo elements. The illustrative embodiment of the damper may include one or more electrical components wherein the electrical components, piezo elements, and/or damper mass may be tuned such that the damper is configured with an electrical resonance frequency corresponding to a mechanical resonance frequency present in a component of the rotary machinery. The piezo elements may be extension/retraction type or bending type, and they may have any orientation with respect to the rotational axis of the rotary machinery depending on the specific embodiment and/or application of the damper.
