Abstract

The shaft is one of the most important parts of rotating machineries. Rotation of the shaft is commonly affected by torsional disturbances, which consequently excite the torsional vibration in the shaft. Such vibration causes fatigue damage and decreases overall performance of the shaft. One of the effective techniques to supress the harmful effect of torsional vibration is to use dynamic vibration absorbers (DVAs). This paper presents a numerical method for determining the vibration of a shaft subjected to harmonic, impact and random torsional excitations.
