A realistic model of the piano hammer-string interaction must treat the action mechanism and string as a single system. In this paper an elastic stiff string model is integrated with a dynamic model of a compliant action mechanism with flexible hammer shank. Action components represented as rotating bodies interact through felt-lined interfaces for which a specialized contact model with hysteretic damping and tangential friction was developed.

- The study analyzes how a sitar string behaves when it hits a parabolic obstacle, focusing on the differences in mathematical equations for the string's free and contacting parts.
- The authors develop a new model using Hamilton's principle to derive a set of equations, which they convert into ordinary differential equations for easier numerical analysis.
- The results, including simulations that mimic real sitar playing, help explain how the string generates a buzzing sound when interacting with the obstacle.
