WebMay 15, 2015 · The quality factor of a mechanical system characterizes the tendency for the system to maintain energy under free oscillations. A system with a high quality factor dissipates only a small amount of energy during one oscillation and thus is well isolated from the environment. WebQm is a parameter proportional to the device under test efficiency in vibrating, and inversely proportional to its damping or internal losses. For power applications, the higher the Qm, …
