On the Creation of the Helmholtz Motion in Bowed Strings
Knut Guettler · 2002
Summary In this study, the conditions for establishing Helmholtz motion in a bowed string are studied analytically and by computer simulations. For simple models of the bowed string, the bow force and bow acceleration are the two operative parameters during the creation of the Helmholtz motion. Parameter spaces for bow force and bow acceleration during the build-up of a regular Helmholtz motion are computed. These spaces have triangular shape in the initial part of the transient. Similar results are observed with more advanced simulation models. PACS no. 43.75.De
