Investigation of toothed shaft from the view of modal parameters

Popis výsledku v původním jazyce

The paper deals with the investigation of toothed shaft from the view of modal analysis, which is a base of dynamic analysis. The gear mechanism is newly designed based on new principle, at which the motion and power are transferred from one input shaft to two output shafts in one direction. Considering that structures vibrate in special shapes when excited at their resonant frequencies, by understanding the mode shapes, all the possible types of vibration can be predicted. The paper aimed to create experimental and computational model of the shaft with subsequent verification of selected theories, to compare results obtained by numerical and experimental modal analysis and to assess the dynamic characteristics of the component with respect to its operating conditions. There are described conditions of both numerical and experimental modal analysis in the paper. The measurements have shown that the values of natural frequencies along with the natural shapes are adequate and comparable within both of the investigation methods. Moreover, from the results it is clear that output shaft should not be subjected to resonance. On the other hand, by means of modal analysis, the number of teeth was specified, that can be risky at the dynamic load of the gear, if the gear ratio changes.
