Principal mechanism. A suspended test assembly acts as a mechanical low-pass filter of ground displacement above its resonance, reducing coupling into precision measurements. It does not block gravitational fields or gravitational waves.
Textbook model: f₀ = (1/2π)√(g/L). Let r = f/f₀. For a viscously damped single-degree-of-freedom base-excited stage, T = √(1+(2ζr)²) / √((1−r²)²+(2ζr)²); output amplitude x = T × A; level change = 20 log₁₀(T) dB.
What is genuine: suspended masses, vacuum isolation, inertial measurement, structural support, optical position sensing and the equations are established scientific concepts.
What is reconstructed: the proportions, flanges, actuator placement, rack layout, material colour, service walkways, and optical arrangement are engineering-inspired rather than manufacturing drawings.
What is simplified: calculations represent one idealized linear stage, not the illustrated cascade; real controls, multiple resonances, seismic spectra, sensor noise, tilt coupling, and isolation geometry are omitted. Animation is illustrative, not a validated scientific simulation.
Numerical labels: the acceleration g = 9.81 m/s² is a textbook approximation; all editable lengths, amplitudes, excitation frequencies and damping values are illustrative; geometry is drawn to arbitrary scaled proportions.
