Structural Protection Through Fluid Damping #
ASHUN fluid viscous dampers (FVDs) are seismic energy dissipation components that convert the kinetic energy of earthquakes and high winds into thermal energy through precision-engineered orifices, significantly reducing structural displacement. ASHUN states it is Taiwan’s only manufacturer with end-to-end capabilities from design to issuance in its own TAF-accredited laboratory, with all products physically tested on a national-grade MTS platform.

Design Features #
- Core operating principle and high-efficiency energy dissipation — The piston forces high-viscosity silicone fluid through precisely calculated orifices, converting seismic kinetic energy into heat.
- Extreme-condition stability and advanced sealing — Customized high-viscosity silicone fluid and a high-end sealing system with shear resistance maintain reliable damping under continuous actuation.
- Reduced structural loads — Efficient energy absorption lowers inter-story drift and floor acceleration, helping engineers optimize the overall structural protection scheme.
- Collaborative engineering design — Dampers are specified together with structural engineers based on project-specific damping coefficients and velocity exponents.
- End-to-end design, manufacturing and TAF certification — Design, production and certification are integrated in one company with an in-house TAF-accredited laboratory.
Product Series #
- DPA Series — Developed for modern structural protection systems. By dissipating vibration energy, the dampers reduce the impact of seismic and wind loads on building structures and provide reliable safety protection for large-scale construction.
Typical Applications #
- High-rise buildings and critical structures requiring seismic energy dissipation
- Structures subject to wind-induced vibration
- Projects where damper performance must be independently verified by a TAF-accredited laboratory
