A damper using viscoelastic material to absorb vibration energy. Steel plates and high-damping rubber are bonded reliably so structural deformation drives rubber shear and dissipates energy.
VED uses no liquid and avoids leakage. It can dissipate small-amplitude wind vibration after reliable structural connection, and can satisfy large-deformation energy dissipation during earthquakes.


Common forms include wall-panel type, axial type, and rotational type. The product thickness is small and can integrate easily with building structures.
Viscoelastic material performance is sensitive to temperature and frequency, so the operating temperature range is selected carefully for stable damping performance.


Wall-panel type uses large steel plates and viscoelastic rubber vulcanized together, then connects to embedded structural components with bolts and welds.
Rotational type uses sector steel plates and viscoelastic rubber at beam-column intersections to dissipate energy through angular deformation.


Axial type uses multiple steel and rubber layers, connected like a viscous damper through pins and ear plates.
