Abstract
Importance of knowing characteristics of rotational systems vibrations is significant, since it is main cause of machine failure. Vibration analysis could facilitate determination of the machine fault. As a part of the research on machine faults and its reflection on the machine behavior, numerical modeling could give excellent starting information for future research. Finite element model of rotational system motor – flexible coupling – rotor is presented in this paper. As a fault analyzed in this paper, misalignment and rotating looseness are used and modelled as external loads. For this modelled rotational system is shown that it is suitable for analysis of rotational machinery vibrations.
