Analytical Study of Coupling Effects for Vibrations of Cable-Harnessed Beam Structures
TLDR
In this article, a distributed parameter model is presented to study the effects of the harnessing cables on the dynamics of a host structure motivated by space structures applications, where the structure is modeled using both Euler-Bernoulli and Timoshenko beam theories.Abstract:
This paper presents a distributed parameter model to study the effects of the harnessing cables on the dynamics of a host structure motivated by space structures applications. The structure is modeled using both Euler–Bernoulli and Timoshenko beam theories (TBT). The presented model studies the effects of coupling between various coordinates of vibrations due to the addition of the cable. The effects of the cable's offset position, pretension, and radius are studied on the natural frequencies of the system. Strain and kinetic energy expressions using linear displacement field assumptions and Green–Lagrange strain tensor are developed. The governing coupled partial differential equations for the cable-harnessed beam that includes the effects of the cable pretension are found using Hamilton's principle. The natural frequencies from the coupled Euler, Bernoulli, Timoshenko and decoupled analytical models are found and compared to the results of the finite element analysis (FEA).read more
