Product Description

Product Description

 

Viscous tuned mass dampers are composed of three parts: a mass system, a spring system and a damping system.
When the viscous tuned mass dampers are installed, the vibration frequencies of the mass systems are adjusted to match those of the structure. As the structure vibrates, the mass systems of the product resonate with the controlled vibration modes of the structure and vibrational energy is dissipated through viscous fluid dampers.
These dampers are primarily employed when the vibrations cannot be dampened by increasing the stiffness of the system or through other direct methods.  They find application in horizontal structures like pedestrian bridges, large cantilevers, and long-span floors, as well as vertical structures such as wind turbines, transmission towers, and television towers. With proper design, tuned mass dampers offer efficient solutions to all these challenges.

Company Profile

 

Hebei Ansha New Material Technology Co., Ltd. is located in Binhu New District of Hengshui City. We specialize in R&D and production of seismic isolation and damping products for both buildings and bridges. Our products include rubber bearings, spherical bearings, friction pendulum systems, fluid viscous dampers, tuned mass dampers, buckling-restrained braces, friction dampers and metallic dampers. In addition, we manufacture bridge expansion joints and fiber-enhanced plastic products.
We have established state-of-the-art physical and chemical laboratories and specialized production lines. Our company operates in full compliance with the ISO9001:2015 Quality Management System, ISO14001:2015 Environmental Management System, and ISO45001:2018 Occupational Health and Safety Management System.
Guided by the anti-seismic design principle of "resisting collapse in a major earthquake, enabling repair in a moderate earthquake, and remaining undamaged in a minor earthquake", we offer our customers a comprehensive array of services. These services include technical consultation, structural analysis and calculation, design optimization, research and development, manufacturing, installation guidance, performance monitoring, maintenance and repair.
