Jarret viscoelastic shock absorbers are innovative devices used for energy dissipation or prestressing of certain industrial equipment, or preservation of civil engineering structures. Douce-Hydro, which took over the Jarret Structures business in 2008, specializing in the design and manufacture of devices to protect against shocks and vibrations, is the ideal partner to supply you with Jarret viscoelastic dampers, perfectly tailored to your needs. How do these dampers work, and what are their applications in the earthquake, civil engineering and industrial sectors?
How do Jarret viscoelastic shock absorbers work?
Jarret viscoelastic dampers are designed to absorb and dissipate the energy generated by seismic forces, protecting civil engineering structures from the potentially devastating effects of earthquakes. These shock absorbers are armed to attenuate the effect of vibrations and significantly reduce the impact of ground movement, a source of instability.
When a seismic force strikes an infrastructure, the viscoelastic material of shock absorbers temporarily deforms, dissipating the energy that causes the shock. By dissipating the energy released, the shock absorber reduces the intensity of the vibrations and preserves the structures or equipment affected.
Jarret dampers are designed to adapt to different levels of seismic intensity. They can also be adjusted to respond specifically to the seismic activity of a given region, depending on its degree of exposure to risk. These adjustments in the design of Jarret dampers enable them to be assigned precise objectives and guarantee a very high level of performance under varying seismic conditions.
What are the applications in the different sectors?
Jarret viscoelastic dampers have a wide range of applications: they are used mainly in the earthquake-proofing and civil engineering sectors, but also in defense, port and river equipment, steelmaking, marine, offshore, space, handling and lifting, special machinery and railways.
In earthquake-prone areas, these shock absorbers increase the resistance of buildings and infrastructure to potential damage caused by earthquakes.
On bridges and viaducts, Jarret viscoelastic dampers help stabilize structures against vibrations caused by traffic and wind. They also reduce excessive oscillation and deformation during and after seismic shocks.
In factories and industrial plants, Jarret dampers protect equipment subjected to excessive, regular and brutal vibrations. They extend their service life and reduce maintenance costs.
