Measurements of some parameters of bowing
Robert T. Schumacher · The Journal of the Acoustical Society of America · 1994
The maximum bow force for Helmholtz oscillations, and the frequency shift as a function of bow force, have been measured for unstopped notes on a variety of violin strings. A bowing machine is briefly described on which data using bowing velocities at 5 and 10 cm/s were obtained. Computer simulations using the standard friction function model of the bowed string were also done. The combination of the measurements and the simulations allow an assessment of the probable validity of the friction curve model of the force between bow hair and string in bowed string motion.
