VIBRATION CONTROL DAMPER AND VIBRATION CONTROL STRUCTURE OF BUILDING CONSTRUCTION

摘要

PROBLEM TO BE SOLVED: To obtain a vibration control damper which dynamically copes with a frequency change in a simple constitution.;SOLUTION: The vibration damper is equipped with: a joint 13 having a first screw-coupling part 15a and a second screw-coupling part 17a which respectively have inverted-screw structures inverted with respect to each other at both ends; a first arm 15 which is screw-coupled to the joint 13 via the first screw-coupling part 15a; and a second arm 17 which is screw-coupled to the joint 13 via the second screw-coupling part 17a. The joint 13 has a mass part 31 having an inertia mass body. The mass part 31 dynamically buffers a vibration energy inputted into the first arm 15 and the second arm 17 by friction forces of both the screw-coupling parts 15a, 17a when the vibration energy is converted into a turning force of the joint 13 via the first and second screw-coupling parts 15a, 17a.;COPYRIGHT: (C)2011,JPO&INPIT
