This paper proposes a digital waveguide model of a bowed string in which the interaction between the bow and the string is modeled using an elasto-plastic friction model. The interaction model is presented, and its advantages with respect to usual static models are discussed. Details about the numerical implementation are addressed. Numerical simulations show that a hysteresis loop in the friction versus velocity plane is created, which is qualitatively compatible with experiments on real instruments and with the behavior of a recently proposed thermodynamical friction model applied to bowed string simulations.

Abstract
This paper proposes a digital waveguide model of a bowed string in which the interaction between the bow and the string is modeled using an elasto-plastic friction model. The interaction model is presented, and its advantages with respect to usual static models are discussed. Details about the numerical implementation are addressed. Numerical simulations show that a hysteresis loop in the friction versus velocity plane is created, which is qualitatively compatible with experiments on real instruments and with the behavior of a recently proposed thermodynamical friction model applied to bowed string simulations.File | Dimensione | Formato | |
