The vibrations of a bowed violin string have been studied since the 19th century. The string was found to oscillate in a simple triangular pattern described by Helmholtz. Today these vibrations are known as stick and slip vibrations caused by friction and have been studied by many researchers. Stick-slip vibrations are self-sustained oscillations induced by dry friction. The theoretical analysis of stick-slip vibrations was solved by Cellular Automaton Method during prior research. However, it is not solved by Modal Analysis Method. In this research, stick-slip vibration is solved by Modal Analysis Method. At the time of slip, as a result of the simulation, it was possible to obtain results by Modal Analysis Method which is reasonable compared with Cellular Automaton Method.
