Metal Composite Damper (MHD)

The metal composite damper is an organic combination of lead-viscoelastic damper and friction damper by using viscoelastic material that not only consumes energy but also has a certain reset function.

Features:

Name Principle Features
Metal damper Damping is produced by plastic deformation of special steel (or ordinary low yield point steel) Simple structure, low cost, reliable performance, basically not affected by temperature, good damping effect

product ADVANTAGE

  • Friction damper

    It mainly includes the middle steel plate, the two outer steel plates and the friction material between the steel plates.

  • Simple mechanical model

    Simple and easy analysis and design of structural vibration reduction.

  • Simple structure and low cost

    Even large earthquakes are not damaged, so there is no need to replace.

  • Damping

    The hysteresis curve is basically rectangular.

  • Stable performance

    Velocity correlation, displacement correlation is small.

  • Good durability

    No post-maintenance required.

  • Energy absorption

    Vertical bearing capacity, horizontal restoring force, damping (energy absorption) trinity.

  • Damping ratio

    Improved rubber formula, the equivalent damping ratio can reach more than 12%.

  • Maintenance costs

    Low maintenance and management costs (no additional damping devices required).

  • Environmental friendly

    HDR high damping rubber has low temperature dependence and is widely used in different climatic regions.

  • Creep properties

    HDR high damping rubber has the same superior deformation performance as natural rubber.

  • Aging resistance

    The surface of the high damping bearing is covered with a rubber protective layer to protect the internal rubber from ozone and ultraviolet rays.

  • Viscous resistance

    It is a kind of damper related to stiffness and speed.

  • Widely used

    It is used in high-rise buildings, bridges, seismic reconstruction of building structures and other fields.

  • Airbag

    The damper absorbs and dissipates the impact energy of the earthquake on the building structure to the maximum extent.

  • Silicone oil medium

    The medium has a small viscosity temperature coefficient, and good radiation resistance.

  • Electrical insulation properties

  • Ozone resistance, corona resistance
