VIBRATION CONTROL BY A TMD USING A ROTATING INERTIA MASS

Abstract

A tuned mass damper (TMD) using a rotational inertia mass has been developed to reduce vertical vibrations of beams and slabs subjected to walking excitations. The newly developed TMD is composed of a spring and a ball screw mechanism with a fly wheel. Vibration tests of a beam structure were carried out to show the effectiveness of the TMD using a rotational inertia mass and compare the test results with those of simulation analyses using a theoretical model.
