Free Vibration Analysis of Rotating Euler–Bernoulli Beam with Exponentially Varying Cross-Section by Differential Transform Method
سال
: 2018
چکیده: In this paper, the free vibration analysis of non-uniform rotating Euler–Bernoulli beam is
carried out. It is assumed that the beam has exponentially decaying circular cross-section.
In order to solve the problem, the differential transform method (DTM) is utilized. Based on our
knowledge, we claim that the recurrence relation presented herein is an elaborate recurrence
relation which has been obtained for ordinary differential equations. Non-dimensional natural
frequencies of the beam are obtained and tabulated for different values of the beam parameters
such as taper ratio and rotating speed. Furthermore, the finite element method (FEM) is
employed to solve the problem. Comparison of the results obtained by DTM and FEM indicates
the accuracy of proposed solutions.
