Viscous annular damper, impact (shock) response
Stopping stroke, peak piston force and peak hydrostatic pressure of an annular viscous damper (outer radius R₀, inner radius R₁, gap h₀) when a mass enters at a given impact velocity, including a relative-eccentricity correction.
No dedicated diagram exists in the legacy archive for response_3.htm — reuses the annular-damper photo from viscous-damper-annular-gap (damping.htm), since both calculators share the identical geometry (outer radius R₀, inner radius R₁, gap h₀), confirmed by damping.htm's own description explicitly covering "when shock loaded".
