Dynamic Analysis of Axially Beam on Visco - Elastic Foundation with Elastic Supports under Moving Load
For dynamic analyses of railway track structures, the algorithm of solution is very important. For estimating the important problems in the railway tracks such as the effects of rail joints, rail supports, rail modeling in the nearness of bridge and other problems, the models of the axially beam model on the elastic foundation can be utilized. For studying the effects of axially beam on the ela...

متن کاملFrequency Analysis for a Timoshenko Beam Located on an Elastic Foundation
It is quite usual to encounter a beam with different types of cross section or even structuraldiscontinuities such as a crack along its length. Furthermore, in many occasions such a beam mayhappen to be exposed to the oscillatory fluctuations. Therefore, any information about its naturalfrequencies may be worthwhile. Amongst the problems of discontinues beam analysis, in this paper aspecial kin...
متن کاملThe analysis of a Beam Made of Physical Nonlinear Material on Elastic Foundation Under a Harmonic Load
ABSTRACT: A prismatic beam made of a behaviorally nonlinear material situated on nonlinear elastic foundation is analyzed under a moving harmonic load moving with a known velocity. The vibration equation of motion is derived using Hamilton principle and Euler Lagrange equation. The amplitude of vibration, circular frequency, bending moment, stress and deflection of the beam can be calculat...
متن کاملA Note on Free Vibration of a Double-beam System with Nonlinear Elastic Inner Layer
In this note, small amplitude free vibration of a double-beam system in presence of inner layer nonlinearity is investigated. The nonlinearity is due to inner layer material and is not related to large amplitude vibration. At first, frequencies of a double-beam system with linear inner layer are studied and categorized as synchronous and asynchronous frequencies. It is revealed that the inner l...
