Andrade Safe — linear viscous SDOF vibration laboratory
Educational synthetic constant-force steady-state model, not machine approval or diagnosis.
Open laboratorio-vibracao.html locally; PT/EN/ES, no external scripts.
Run Python 3 modelo-vibracao.py; CSV uses SI units named in headers.
Peak and sinusoidal RMS differ. Changing mass at fixed natural frequency recalculates stiffness.
The curve includes the analytical resonance maximum and local refinement. Time response is five steady periods, not startup.
