Vibration dampening is required wherever resonance is generated, or where the effects of shocks need to be rapidly weakened. Vibration insulation should not be confused with vibration dampening. Efficient vibration insulation can only be achieved with a corresponding frequency adjustment.

THE EFFECT OF VIBRATION DAMPENING
Vibration conditions: Dampening with rubber differs significantly from e.g. viscous dampening.
In the frequency range 10-200 Hz, the shape of the force/movement diagram (the dampening ellipse) is constant, and independent of the excitation frequency.
The dampening factor is, in connection with rubber, frequency dependent, and moves towards zero with an increasing frequency.
This means that when it comes to very small movements, the dampening effect of the rubber is insignificant, and is unlikely to influence insulation effects.
On the other hand, for viscous dampening, the dampening effect increases with an increasing frequency, which leads to a deterioration of the insulation effect.
Rubber springs are ideal as vibration and noise silencers.
The vulcanised rubber elements have a bond strength between metal and rubber of 130 kp/cm².
Ellegaard has serviced Danish industry since 1954 and has many years of experience in maintenance and repair of rubber. Through 60 years, we’ve accumulated an impressive knowledge across many industries, and we service transport systems all over the country.
