📉 Vibration Isolator: Transmissibility, Resonance and Time Response (2D side view)

2D side view of a platform on a spring and damper above a vibrating floor. Set platform mass, stiffness, damping ratio, floor frequency and amplitude, and see the platform motion in time, the transmissibility curve, attenuation in decibels and the natural frequency. A time-domain integration is checked against the closed form. Same relations as the 3D page, with four in-page numerical checks.
