Mid-Stroke Length

Technical Data The FVD-B Series dampers are typically utilized on bridge and base isolation platforms requiring a long cycle life. This custom orifice designed damper provides the desired force versus velocity relationship symmetrically in both tension and compression directions, thermal compensation, and easy preventative maintenance inspection. Note: 1. Various stroke lengths available. Pin-Pin length at mid-stroke position can be determined by adding 2.5x the stroke length change. 2. Velocity exponent a is available from 0.2 - 1.0 3. Weight and dimensions are for reference only. Consult ITT...

Fluid Viscous Damper FVD-B Series Technical Data Shown below are graphs depicting the damping force versus the velocity for various damping coefficients and velocity exponents. Refer to page 11 for how to specify the damping characteristics when ordering.
