How does a pendulum tuned mass damper
Webuntuned whirling pendulum can stabilize an unstable mode. In the present work, we attach a light, nonresonant, secondary system that can exhibit two limit cycles: one stable and one unstable. We note that the attached system, being nonresonant, does not require precise tuning. Figure 1 (left) shows a schematic of the coupled WebFeb 1, 2006 · The PTMD used in this study acts as a passive tuned mass damper. An equivalent single-degree-of-freedom model for the PTMD is developed and used to derive the equations of motion of the coupled PTMD-floor system. The optimal design parameters of the PTMD are found using an optimization algorithm.
