The dynamic stability of a stepped beam subjected to a moving mass is investigated in this study. The equations of motion for transverse vibrations of the beam are developed in distributed parameter and "nite element forms. The impulsive parametric excitation theory is used to predict the stability

A simple procedure based on the finite element method has been developed for treating the dynamic analysis of beams on an elastic foundation subjected to moving point loads, where the foundation has been modelled by springs of variable stiffness. The effect of the speed of the moving load, the found
In this paper, an exact dynamic stiffness element under the frame work of finite element approximation is presented to study the dynamic response of multi-span structures under a convoy of moving loads. A dynamic model coupled with a FFT algorithm is developed. The model is highly efficient for calc
The dynamic behavior of multi-span non-uniform beams transversed by a moving load at a constant and variable velocity is investigated. The continuous beam is modelled using Bernoulli}Euler beam theory. The solution is obtained by using both the modal analysis method and the direct integration method
The problem of vibration of engineering structures resulting from the passage of different types of loads is of great importance. Vibrations of this type occur in bridges and railways excited by vehicles, piping systems subjected to two-phase flow, and machining operations where high axial speed is
