In this article, the residual vibration of a simply supported beam with moving mass is studied. The moves from starting point to an end on trapezoidal velocity profile having accelerating, constant and decelerating time intervals. mid-point after stops analyzed. mathematical model system developed using finite element (FE) theory. Newmark method used for solution FE dependent matrices because m...

At GSI we are presently developing an alternative method for a very fast (in order of few ms) range adaptation for radiotherapy of moving organs [1] with scanned ion beams to the existing 3D online motion compensation (3DOMC) [2] system. The range adaptation can be achieved by deflecting the ion beam (with the energy E0, see Fig.1) to different positions on a static wedge-shaped energy degrader...

this paper presents the high order frequency-amplitude relationship for nonlinear transversely vibrating beams with odd and even nonlinearities using homotopy perturbation method with an auxiliary term (hpmat). the governing equations of vibrating buckled beam, beam carrying an intermediate lumped mass and quintic nonlinear beam are investigated to exhibit the reliability and ability of the pro...

number of states equals to the number of the particles in the beam. This definition basically corresponds to assumption that the beam has zero temperature. We will simply calculate the number of allowed states. The second approach, indeed, uses the definition of the beam temperature in a moving system of reference. We compare the emittance restrictions obtained with these two approaches. Ultrar...

We introduce a radial basis collocation method to solve axially moving beam problems

This paper presents the high order frequency-amplitude relationship for nonlinear transversely vibrating beams with odd and even nonlinearities, using Homotopy Perturbation Method with an auxiliary term (HPMAT). The governing equations of vibrating buckled beam, beam carrying an intermediate lumped mass, and quintic nonlinear beam are investigated to exhibit the reliability and ability of the p...

Ports are the most important economic, political and military bottlenecks. This puts shoreline structures (port) in the class of important structures and they have a crucial role in the countries’ life. Pile and deck wharf and their access bridges and offshore deck (jetties), are one of the parts which are supplier of coupling between the land and the waterfront. Correct and exact estimation of...
