Abstract
Rapid evaluations of the frequencies of small-amplitude transverse vibrations of a loaded hollow biconic beam with a linearly varying wall thickness are determined by means of an analytically approximate approach. The natural frequencies are treated as those of an unloaded double-tapered circular beam perturbed by the mass of a light load. It is found that the first-order coefficient of the frequency-parameter change is independent of mode frequency.
