Self-tuned mass damper and system comprising the same

Jarkko Keinänen (Inventor), Kalle Vehviläinen (Inventor)

Research output: PatentPatent


A simple self-tuned mass damper is hereby proposed for a broadened frequency band and which can be adapted to large and expensive structures as well as small and inexpensive structures alike. The novel self-tuned mass damper includes an auxiliary mass and a non-linear suspension, which is configured to connect the auxiliary mass to a vibrating structure. The mass of the auxiliary mass and the stiffness of the non-linear suspension are selected such that the natural frequency is at least 6 Hz and that the amplitude of the relative displacement of the auxiliary mass in respect to the vibrating structure is at most 12 mm.
