Vibration Mitigation Devices
ModelTypical InstallDescription
GERB Viscoelastic DampersUses bituminous or silicone viscous fluids to provide a 6 DOF zero maintenance damper for controlling pipe vibrations. ANCO provides custom clamping and installation. The GERB units can also be used with helical springs to provide full base (3 DOF) isolation systems to prevent machine vibrations from propagating to nearby equipment.
Fluid SnubbersReduces structural vibration using energy absorbing fluid snubbers.
Isolation PlatformsProvides seismic isolation for critical and costly items such as computer servers, medical instrumentation, telecommunication equipment, and art objects. Four sizes are available, covering equipment weights from 50 to 1000 kg. Multiple units can be combined to increase payload. Stokes of 150-200 mm in dual horizontal directions are available.
TL3 Energy AbsorbersLow cost, long stroke, single event energy absorbers that are used to protect electric transmission lines from catastrophic progressive failure. The TL3 can be used to protect any critical structure from singular dynamic events (e.g., parachute deployment, ship mooring, and tow lines). The TL3 behaves as a rigid compact link until a preset trigger force (1, 2, 5, 10, 20, 50, or 100 tons) is reached.

Motion Platforms Motion tables are shaking tables which typically have large displacement capacity (up to +/- 2 m and +/- 45 degrees) and operate at lower frequencies (below 5Hz). Motion tables are used for simulating ship and aircraft motion and the long period effects of earthquakes.  Quasi Static Testing Computer controlled servo-hydraulic multi-actuator testing systems allow for fatigue testing, quasi static testing including Pseudo-Dynamic Testing (PST).Components of a typical quasi static testing system include:• Structures laboratory with strong floor and walls with attachment inserts. • Multiple actuators with static force rating of 100 kN -1000 kN. Stroke from +/- 100 mm to +/- 400 mm. Peak velocity of 1 cm/s -10 cm/s. • Vane type bridge load cells with 150% force measurement overload capacity. • Magnetostrictive coaxial displacement transducers. • Zero maintenance PTFE swivels or steel-on-steel lubricated swivels on base and piston, with client specified bolt pattern. Swivels have +/- 100 degree/+/-8 degree capacity. • Hydraulic power supplies rated for fatigue operation and 15-180 GPM. • Hydraulic power supply with capacity of 30-300 GPM (110-1100 L/min) at 3,000 psi (21 MPa). • Hydraulic hoses to place the actuators up to 30 m from the strong wall or strong floor local manifolds (with quick release connectors). • 5-15 GPM two-stage servo valves (option for larger valves). • Frequency response 0-20 Hz. • PC-based digital control system (ANIPC and TRIDENT) with up to 8 actuators control and acquire up to 128 channels of data. • Additional strain or displacement measurement transducers, as required.Economical Education Tables Small, economical shaker tables for research laboratories, universities, colleges and high schools. For this purpose, a series of horizontal, all-electric shake tables with the closed loop DANCE controller or the economical, open loop FOXTROT controller is available.

R-201 R-202Electrodynamic Shaker SEV and SEW series of Electrodynamic Shaker produces vibration based on the principle of magnetism. The SEV series is air cooled and SEW series is water cooled, respectively. The product portfolio covers all ranges of shaker, from 10 kgf up to 32000 kgf and beyond.An Electrodynamic Shaker has two separate coils, one is stationary and the other is dynamic. A stationary magnetic field is produced from the stationary or field coil inside the shaker body and a dynamic magnetic field is produced from the dynamic or armature coil winded on the armature. Interaction of these two magnetic fields causes the freely suspended armature to move. This principle of magnetism is based on Fleming’s Left Hand Rule. The products are categorised as Low-Medium-High Thrust series:
