Spring Units with Viscodampers

GERB Vibration Control Systems Pvt Ltd offers Spring Units in combination with Viscodampers® that can considerably reduce such vibration levels and structure-borne noise typically measured in velocities. A spring supported system – in this case a press – with a vertical natural frequency of approximately 3-6 Hz and about 5-20% of velocity-proportional critical damping will usually lead to a 70-90% reduction of vibration velocities compared to the expected velocities in case of a conventional installation using grouting or hard rubber mounts. Such a large reduction of vibration levels improves not only the working conditions for plant, sensitive machines, tool room, but also the living conditions of neighbours. Spring units combined with Viscodampers will not only guarantee stability for the machine, but also ensure that the machine quickly returns to zero motion after each stroke hence even automated feeding will cause no difficulties.

Since the dynamic forces transmitted from the press to the sub-foundation are greatly reduced by the vibration isolation system, the design of the sub-foundation can be limited to the static loads which will lead in a major way to lower construction cost of the foundation. Spring support is, however, not only a matter of vibration control for the surrounding. Vibration measurements on presses themselves and long time practical experience have shown that wear and tear of the press will also be reduced by spring support, resulting in less maintenance and a longer lifetime of the press and especially its dies. There are numerous installations in India and across the globe for all kind of such machines for capacities ranging from 10 T to 16000 T at almost all renowned automobile companies and its ancillaries.
