Free Vibrations of the Planar Gantry-like Structures

Abstract

This paper deals with eigenfrequencies of distributed-parameter system within the form of gantry-like structure with cantilever part. The individual members of the structure-framework are assumed to be governed by the transverse vibration theory of Euler-Bernoulli beam. It is obtained postulation of frequency equation while solutions are obtained numerically with in-house software, for several cases of structures. Also, it is done finite element postulation of the gantry-like structure as discrete-parameter system for analyzing the free undamped vibrations. Thus, it stands for two folded presentation. It is done verification of postulated algorithms.
