Enhanced Tribological Modelling of Violin Rosin

Abstract

Accurate simulation of the motion of a bowed violin string requires a reliable tribological model for rosin, with which the bow-hairs are coated. None of the models proposed in the past have given entirely satisfactory results. An enhanced model is proposed here, which combines influences from the contact temperature and the sliding speed. Transient vibration predictions using this model are compared with earlier experimental measurements in the “Guettler diagram”, demonstrating better agreement than with earlier models.
