Control of Bending-Torsion Structural Vibration Using a Pair of Hybrid Mass Dampers

概要

論文の詳細を見る
A pair of hybrid mass dampers installed at both edges of the top of a six-stage structure comprising floors and pillars (approx. 3.7 m high, total weight approx. 2.5 t) was tested for its performance in reducing bending and torsional vibrations. The performance was compared between the control principles of (a) decomposing sensor signals into bending and torsion ("coupled control") and (b) separating the sensor signals ("individual control"). Both control principles proved to ensure high damping performance for bending and torsion. Between the two principles, coupled control promises better performance in general, as indicated from an example of the test results.
