Constructive provision applied to damper mass tuned with control of variation of mass, stiffness and damping

摘要

Constructive provision applied to damper mass tuned with control of variation of mass, stiffness and damping of the present invention is available on the constructive of a shock absorber mass tuned to control vibrations in structures of the slabs or tiles Concrete, by means of the dissipation of vibrational energy by frictional forces.Is intended for applications in places that require small size, flexibility in the size of the damping system and applications that require adjustment of variation of mass, stiffness and damping.It is comprised of a base upper (2), responsible for fixing the damper to the structure through anchor bolts (1) connected to a lower base (11) by axes of support (3), in addition to contain metal plates (4), screws of the outer (5), rings, guide (9), springs (1) , aligners (12), the axes sinks (6), bolts (7) and regulators of friction dissipating blocks (8).
