A tuned mass damper comprises a mass (1) restrained to a structure (2) through supporting means (3) suitable to allow a pendulum motion of said mass (1) when said structure (2) is subject to an external force, as well as damping means suitable for absorbing a portion of the kinetic energy of the moving mass (1). The supporting means (3) comprise at least one bearing (3) provided with a concave cylindrical sliding surface (3a) and the damping means are made as a coating of a controlled friction material of said sliding surface (3a). |
