Torsional Oscillation

The thesis only focuses on reducing torsional vibrations of the machine shaft, not considering other vibrations, such as axial vibrations, bending vibrations, etc. The calculation when taking into account these vibrations is mentioned by the author in the next research direction of the thesis. 4. ...

 Consider the machine shaft model with 3 degrees of freedom (N=3) The amplitude response of the generalized coordinates is expressed as:    ˆ e I  t (4.40) 1 1 2 2    ˆ e I  t 3 3    ˆ e I  t (4.41) (4.42) I  t  a   ˆ a e (4.43) Substituting ...
