Abstract EN
The purpose of this paper is to present the exact solution for free torsional vibrations of a linearly tapered circular shaft carrying a number of concentrated elements.
First of all, the equation of motion for free torsional vibration of a conic shaft is transformed into a Bessel equation, and, based on which, the exact displacement function in terms of Bessel functions is obtained.
Next, the equations for compatibility of deformations and equilibrium of torsional moments at each attaching point (including the shaft ends) between the concentrated elements and the conic shaft with positive and negative tapers are derived.
From the last equations, a characteristic equation of the form [H]{C}=0 is obtained.
Then, the natural frequencies of the torsional shaft are determined from the determinant equation |H|=0, and, corresponding to each natural frequency, the column vector for the integration constants, {C}, is obtained from the equation [H]{C}=0.
Substitution of the last integration constants into the associated displacement functions gives the corresponding mode shape of the entire conic shaft.
To confirm the reliability of the presented theory, all numerical results obtained from the exact method are compared with those obtained from the conventional finite element method (FEM) and good agreement is achieved.
