An interactive simulation of resonance in driven oscillating systems, built with SceneryStack. Visualize driven mass-spring systems and Chladni plate vibration patterns.
- Single Oscillator — driven damped harmonic oscillator with spring presets and frequency sweep
- Multiple Oscillators — 1–10 oscillators with different natural frequencies driven together
- Phase Analysis — phase lag and phase-space plots near resonance
- Chladni Patterns — particles on vibrating plates revealing nodal lines and mode shapes
- Real-time controls for mass, spring constant, damping, driving frequency, and amplitude
- Configurable phase-space graphs, trace mode, and 25+ analytical properties
- English, Spanish, and French UI with multiple color profiles and PWA support
