Concept for a bounce & roll mode damper for the quad suspensions

Document type:

Other Versions:
The feasibility of using tuned mass dampers to passively damp the bounce and roll modes of the quad suspension is explored in Brett Shapiro’s note LIGO-T1500271. That document contains calculations of the damping and thermal noise performance of a tuned mass damper applied to the tips of the UIM blade springs, as a function of several parameters of the damper. This document contains a concept for a specific design of a damper, based on the calculations of T1500271.
