Description
Product Description
The ASHUN DPA Series Fluid Viscous Dampers break away from traditional static anti-seismic concepts that rely solely on reinforcing beams and columns, utilizing fluid dynamics to actively dissipate vibration energy. This not only mitigates the direct impact of seismic waves and reduces metal fatigue risks in structural components but also significantly enhances overall structural resilience during severe tremors.
These dampers feature excellent environmental adaptability. Their damping characteristics remain stable and immune to external temperature fluctuations, operating smoothly from minor wind-induced vibrations to large-scale earthquakes. Paired with versatile end-connection configurations, the DPA series offers high customization flexibility and can remain in service after major seismic events following evaluation, demonstrating exceptional protective efficiency and product lifecycle.
Product Features
- Thermal Stability: Damping characteristics remain unaffected by external climate and temperature variations, ensuring consistent protection standards across all seasons.
- Smooth Operation: Exhibit linear and stable energy dissipation from minor wind pressures to large-displacement earthquakes.
- Durable & Reusable: Feature excellent durability under repeated actuation, maintaining structural protective capabilities even after major seismic waves.
- Flexible Customization: Provide versatile mounting interfaces and support advanced engineering project requirements, including variable damping force control.
