Özet
Aim of this paper is to show that vibrations of 10 degree of freedom (10 DOF) half rail vehicle models obtained by both mechanical mechanism and equivalent electrical circuit are identical. Firstly, the system was modelled and then a free body diagram was formed. Afterwards, motion equations of the system were determined using Lagrange's method, mechanical circuit was constructed using force equations and its equivalent electrical circuit was obtained using Kirchoff current law (KCL) and force-flow similarity. Then, a schema was formed by means of MATLAB Simulink to analyse the vibrations of the rail vehicle model. To make simulations, the speed of the rail vehicle model was selected as 400 km/h. As input, track irregularities in American Railway Standard and non-random irregularities were applied to all the wheels separately. As a conclusion, it was observed that the signals taken by both the mechanical and its equivalent electrical circuit appeared similar and the vibration analysis of a complex mechanical system can be modelled not only mechanically but also electrically.
