Abstract

This paper is focused on the study of motions of non- prismatic rotating Timoshenko beams traversed by constant and harmonic variable magnitude moving loads. The versatile Galerkin's method and the integral transform techniques were employed to treat the coupled second order partial differential equations governing the motion of the vibrating system. Numerical analyses in plotted curves are presented. The analyses depict interesting results on the effect of some structural parameters such as foundation moduli, prestressed forces and circular frequency on the dynamic behavior of non- prismatic rotating Timoshenko beams under the actions of moving loads at time dependent speed. The resonance condition of the dynamical systems is also established.
