Abstract

Chordwise bending vibration characteristics of rotating double tapered beam have been investigated. Considering the assumed modes method, potential energy and kinetic energy expressions are derived from a set of hybrid deformation variables. The system of equations of motion are derived by using the Lagrange’s approach based on Euler–Bernoulli beam theory. Numerical examples are considered to investigate the effect of taper ratio, hub radius ratio and rotational speed on chordwise bending natural frequencies of the rotating taper beam. To establish the validity of the formulation, initially the results were compared with those of the earlier reported works. It has been observed that the results are in conformity with those reported in the literature.
