📈 Triaxial Seismometer: Proof-Mass Resonance and Transfer Function (2D)

2D front view of three orthogonal seismometer proof masses on springs, shaken by the ground. Choose sine, sweep or pulse excitation, set natural frequency and damping, and compare the live motion with the resonance curve and phase lag. Uses the same model file as the 3D page, with four in-page numerical checks.
