What actually isolates vibration?
A massive, rigid platform is mechanically decoupled from a moving base by compliant supports and damping. Six visible mounts share the illustrative total vertical stiffness. A real laboratory design also controls multiple rotational and horizontal degrees of freedom.
Textbook relations
ωₙ = √(k/m), fₙ = ωₙ/(2π), ζ = c/(2√(km)), and r = ω/ωₙ.
For harmonic base displacement: T = √[(1+(2ζr)²) / ((1−r²)²+(2ζr)²)]. Peak isolated amplitude is Y = T·A; peak acceleration is a = ω²Y. The independent check evaluates √[(k²+(cω)²)/((k−mω²)²+(cω)²)], using physical units.
Evidence boundaries
Genuine scientific features: isolation, sensing, flexure alignment, inertial reference concepts, and passive vibration transmissibility. Engineering-inspired: pedestal geometry, proprietary-looking service routes, nested cradle and optical payload. Simplified: all six mounts collapsed into one linear vertical mode, steady-state harmonic forcing, no rotational coupling, no finite-element stresses. Speculative: active piezo correction hardware and its visualization, which is not included in the passive physics equations.
Values are illustrative, with no claim of real facility specifications. Motion is visually exaggerated; animations are educational illustrations, not experimentally validated simulations. Model geometry is scaled and non-manufacturable.
