The invention relates to a tuned mass damper which has variable rigidity and can therefore be tuned and adjusted in a controlled way to different excitation frequencies arising in the system or machine to be damped. The variable rigidity is achieved by the arrangement of appropriately placed compressible free spaces (06) which can be filled with elastomer material (05) in a controlled way. The invention relates in particular to such tuned mass dampers according to the invention which are capable of damping, by means of hydraulic and elastic means, the vibrations generated by different frequencies in that the rigidity of the elastic means can be changed in a controlled way. |
