The application of self-oscillation in wire gauges

Grzegorz Cieplok, Łukasz Kopij
In the presented paper, an original solution to the system maintaining vibrations of a wire
transducer, which has been based upon the phenomenon of self-oscillation, is described.
The vibrations generated in this manner do not fade in time, are resistant to disturbances
and allow measurement of the signal rapidly changing in time. The dynamic equations and
numerical simulations of motion of the wire interconnected with the van der Pol oscillator
are presented. Based on the conceptual model, a laboratory stand has been built, which
served to verify properties of the presented solution and possibilities of useful applications.
