Viscoelastic damper – type VD

VD type viscous damping shock absorber

Viscoelastic damper – type VD Overview -

Bitumen-based media suited for large damping parameters (d = up to 554 kNs/m at 5 Hz) and operating temperatures from +10 °C to +40 °C in a working range of ΔT = up to 20 °C

(depending on the bitumen type).

20°C bitumen

30°C bitumen

40°C bitumen

Further bitumen types up to 80°C on request
Viscoelastic damper – type VD Advantage +
Viscoelastic damper – type VD Performance +
Key parameters required to define a damping solution are as follows:

operating temperatures [°C], i.e. the lowest and highest expected temperature of the vibrating system and the environment

resonance frequencies [Hz] of the vibrating system

amplitude [mm] of the vibrating system

mass [kg] of the vibrating system between two fixed points

cold / hot displacement
