Mechanics of the Contact Area Between a Violin Bow and a String. Part I: Reflection and Transmission Behaviour
A detailed physical model of behaviour in the contact area between a violin bow and a string is developed and explored. The model takes into account the finite width of the bow, the bending stiffness of the string, the longitudinal bow-hair compliance and the torsional motion of the string. It is designed for implementation in an enhanced numerical simulation of the bowed-string action, the topic of two companion papers [1, 2]. This paper describes an analytical investigation of the wave reflection and transmission behaviour, when a wave on the string is incident on the bow. The predictions are compared with experimental results by Cremer , Lazarus and Eisenberg . Comparison shows that longitudinal bow-hair compliance has a large impact on the reflection and transmission behaviour and that sensible modelling of the finite width of the bow requires modelling of the bow-hair compliance. In general, bending stiffness plays a minor role.
