Singing Bowl Vibration: Friction Excitation Lab (2D)

2D companion to the 3D Singing Bowl simulator: a friction-driven Van der Pol self-oscillator excites a real ring-mode of a bronze bowl, showing the standing-wave nodal-diameter pattern deform the rim and generating an actual WebAudio tone at the computed fundamental frequency.

⚙ Under the hood

A 2D companion to the 3D Singing Bowl simulator built on real friction-oscillator physics: a Van der Pol self-oscillator models the stick-slip grip of a mallet circling the rim, driving a genuine ring-mode standing wave (m nodal diameters) whose fundamental frequency is computed from the bowl's radius, wall thickness and mode number, sounded live through WebAudio.
