What isolates the instrument?
A sprung suspended mass attenuates mechanical base vibration at excitation frequencies sufficiently above its natural frequency. Spring and damping forces provide restoration and energy dissipation. The displayed six-column, flexure and actuator arrangement is an engineering-inspired, not validated, layout.
Gravity itself is not shielded: the name describes mechanical isolation for delicate gravity-related measurements.
Equations used
fₙ = √(k/m) / (2π)
r = f/fₙ
T = √[(1+(2ζr)²) / ((1−r²)²+(2ζr)²)]
G = 20 log₁₀(T) dB
Independent complex dynamic-stiffness check: T = |k+iωc| / |k−mω²+iωc|, with c=2ζ√(km) and ω=2πf. This describes textbook single-degree-of-freedom displacement transmissibility under harmonic base motion, not full six-axis dynamics.
Honest representation
Genuine scientific features: inertial sensing, kinematic flexures, passive isolation, active reaction-force concepts and optical displacement monitoring.
Engineering-inspired reconstruction: bay arrangement, structural proportions, vacuum-enclosure access, service platforms, and component placement.
Simplified education: a single equivalent stiffness, mass and damping ratio; no identified control law, sensor noise budget, gravitational gradient measurement or stability proof.
Speculative: the fictional instrument arrangement and decorative operational traces. Animation amplitude is visually exaggerated and is not a validated dynamic simulation.
