Key features

Output force strongly correlates with moving speed. Resistance is low at low speeds, while damping force rises significantly under high speed deformation caused by major earthquakes or strong winds.

Only provides additional damping with barely increased structural stiffness. Non change natural period or static inner force distribution, bringing minimal intervene to the original structural system.

Features rectangular hysteresis loop with excellent energydissipation capacity. It works under minor earthquakes and wind vibration instead of only major earthquakes.

Damping coefficient C and velocity exponent can be adjusted to meet requirements for seismic resistance, wind resistance and combined seismic wind control.

Silicone oil is enclosed inside the cylinder. Qualified products achieve long term leak free performance with a 50year design service life and basically maintenance free operation.

Hinged ends allow certain rotation angles to release additional bending moments from installation and structural deformation, preventing bending failure of the damper.

AI-Powered supplier vetting

SummaryThe supplier demonstrates professional technical and R&D capabilities, including 3D software design, ODM/OEM services, broad customization, and specialized testing and production equipment. Its business scope covers metal products, construction fittings, hardware, metal structures, and rubber products. Quality-related evidence is positive: ISO9001 certification, quality assurance, traceability, and documented corrective-action and complaint procedures. The supplier reports inventory capacity, qualified service-capable suppliers, and one-month lead times in both peak and off-season periods. However, it lacks a valid manufacturing-capacity contract with associated subcontractors, overseas warehouses, overseas showrooms, overseas agents or branches, and offline trade-show participation. Innovation evidence is mixed because no new product was reported in the past year and no SDK is available, although patents and university cooperation are stated. Financial credibility cannot be determined from the provided...

Supplier typeThe supplier identifies as a professional technical supplier and operates across R&D and manufacturing of metal products, construction fittings, hardware, metal structures, and rubber products. This supports classification as a technical manufacturer with a broad industrial product scope.

CertificationsThe company description states that the supplier is ISO9001 certified and holds more than 100 national patents. ISO9001 is explicit evidence of certification, although no additional certification details are provided.

After-Sales capabilityThe supplier has documented procedures and followed records for corrective and preventive actions and customer complaint handling. This is direct evidence of an established service-response mechanism, while no specific response times or warranty terms are stated.

R&D capabilityThe supplier provides R&D, 3D software design, ODM, and OEM services, and reports more than 100 national patents plus university cooperation on seismic isolation technology. However, it reported no new products in the past year and has no available SDK, so the evidence supports technical innovation capacity but not all forms of product or software innovation.

Production capacityProduction evidence includes broad manufacturing business scope, specialized testing and production equipment, inventory capacity, 17 qualified suppliers for service capability, and stated one-month lead times in both peak and off-season. A limitation is that no valid manufacturing-capacity contract exists with associated subcontractors, which creates a documented capacity-governance weakness but does not negate the stated in-house capability evidence.

Customization capabilityThe supplier explicitly offers customization from samples, designs, full customization, minor customization, and flexible customization, supported by 3D software design services and listed design and production equipment. This is clear evidence of broad customization capability.

Client casesThe supplier states that it is qualified to cooperate with China Communications Construction, CSCEC, and China Railway, and that it provides OEM services for popular brands. These statements indicate experience or qualification involving major customers, although no project details, order scope, or verifiable case outcomes are provided.

Product Q&A

Q:Working principle

The VFD viscous damper is a velocity dependent passive energy dissipation seismic mitigation device. Filled with highly stable silicone oil medium inside, it converts kinetic energy generated by earthquakes and wind induced vibration into heat for dissipation through fluid throttling friction. It produces no additional static stiffness and will not alter the natural vibration period of the structure.

Q:Its limitation

Demanding sealing requirements. Oil leakage leads to total loss of damping performance, requiring strict manufacturing and inspection. Viscosity of silicone oil is temperature sensitive; special damping medium is needed for extreme high and low temperature environments. Only dissipates vibration energy, no limiting function or lateral stiffness. Extra limiting components shall be equipped if displacement limiting is required.

Q:Typical service scenarios

Super high rise and high rise public buildings; large span exhibition venues and gymnasiums; steel structure connecting corridors and pedestrian overpasses Bridges (girder bridges, arch bridges); seismic retrofitting of historic buildings; vibration reduction foundations for industrial equipment
