Influence of a bow of finite width on bowed string motion : numerical modelling and experimental evidenceR. PITTEROFF and J. WOODHOUSE

An enhanced physical model of the bowed string presented previously [l] is explored. It takes into account : the width of the bow, the angular motion of the string, bow-hair elasticity and string bending stiffness. The results of an analytical investigation of a model system - an infinite string sticking to a bow of finite width and driven on one side of the bow - are compared with experimental results published by Cremer  and reinterpreted here. Comparison shows that both the width of the bow and the bow-hair elasticity have a large impact on the reflection and transmission behaviour. In general, bending stiffness plays a minor role. Furthermore, a method of numerical simulation of the stiff string bowed with a bow of finite width is presented along with some preliminary results.
