Merenje torzionih oscilacija pomoću mernih traka

In this work the measuring method of torsion vibrations is presented according to the measurement of torsion stress using strain gages. This method is particularly suitable in checking the system elements strain level that transfers changeable torsion moments and oscillate torsionally. Besides that, the system elements critical velocity rotation can be estimated, followed by the resonant strain and problems in the function of that system such as: amplified noise, wearing-out of gears, fatigue crack, damage and break of shafts and junctions etc. The measuring chain is proposed in which the central part is a contemporary mobile system Spider 8, which enables measurement, processing and displays measured results on a computer.
