Title:
TUNED MASS DAMPER
Document Type and Number:
WIPO Patent Application WO/2012/053091
Kind Code:
A1
Abstract:
A tuned mass damper (1) is characterized by comprising: a variable inertial mass device (20) that variably controls the inertial mass of a damper mass (21); an elastic body (31) that couples a rotating shaft (10) rotated by power transmission and an input member (21C) of the variable inertial mass device (20); and a variable damping force device (40) that variably controls a damping force to the elastic body (31). Thus, the tuned mass damper (1) produces an effect that vibration can be appropriately reduced.
