Abstract: It is assumed that a beam made of material has a physical nonlinear behavior. This beam is analyzed under the moving concentrated and distributed continuous loads. The vibration equations of motion are derived from the Hamilton's Principle and Euler–Lagrange Equation. In this study, the amplitude of vibration, circular frequency, bending moment, stress and deflection of the beam has b...

Recent developments in the field of high speed rail have heightened the need for improving of railway bridges under the passage of high speed trains. However, little attention has been paid to influence of significant parameters playing a key role in dynamic behavior of such bridges. This paper seeks to fill such a gap by carrying out finite element (FE) analysis on an existing railway bridge. ...

The MATLAB based simulation on simulink platform is presented for Single Phase Cascaded symmetric Multilevel Inverter for 5 levels. Theoretical study is done for the classification of multilevel inverter. And also the study is done for the classification of modulation scheme for multilevel inverter. Modulation scheme used for single phase symmetric multilevel inverter is fixed frequency multica...

This project proposed the new distortion power quality index to replace the previously proposed index. Its computation was carried out based on the load composition rate (LCR) and Euclidean norm of total harmonic distortions (THDs) of the measured voltage and current waveforms at the point of common coupling (PCC). Based on the proposed PQI, the harmonic pollution ranking, which indicates how m...

The dynamic response of the Timoshenko beam resting on an elastic foundation subjected to harmonic moving load using modal analysis (MA) was investigated. method MA employed obtain a closed form solution this class dynamical systems. In order use MA, accurate information is needed natural frequencies, mode shapes and orthogonality shapes. A thorough literature survey reveals that has not been r...
