In addition to custom designing and fabricating tuned mass dampers and tuned vibration absorbers for different vibration control applications, DEICON offers a compact, modular tuned mass damper (TMD) designed with the needs of floor vibration control in mind. These TMDs can be installed either on or under the vibrating floor (e.g., in the joists cavity).

DEICON tuned mass dampers have a moving mass of about 100 lbs (45 Kg). They are tuned at DEICON to a frequency between 6-12 Hz and fine tuned at the installation site (either by DEICON representative or the client). TMDs with tuning frequencies less than 6 Hz are custom-designed and built by DEICON. DEICON tuned dampers can be readily added to a new floor or one that is already designed and/or built.

Besides the tuning frequency, the effectiveness of a TMD depends on the mass ratio of the TMD to the floor and the amount of damping built into the TMD. The mass ratio of DEICON TMDs can be changed by using a number of these modular 100 lb (45 Kg) TMDs assembled into larger TMD units to suit different size floors. Thru the use of proper material, a substantial amount of damping is built into DEICON TMDs.

Although developed primarily for floor vibration control, DEICON TMDs can be used in other structural damping applications with similar dynamics as those of floor systems.
