Torsional vibrations of multi-cell tubes

Abstract

This paper presents torsional vihraTion analYJis of multi-cell tubes. The main difference between the single and multi-cell tube analysis lies in the determination of the cross-sectional constants. Derivation of cross-sectional constants, involved in the governing equations, is illustrated by considering a four-cell tube. The improvement, in the estimation of the natural frequency by the present proposal, is brought out by comparing the theoretical value with the experimental observation in a specific case.
