A Methodology to Estimate the Center of Oscillation and the Center of Mass of a Railway Vehicle

Abstract:

The paper proposes a model in order to estimate the location of the center of oscillation and mass of railway bogies or vehicles in order to place in the correct position all the equipments inside the coach. The location of this point is very important for the comfort coefficients regarding passenger coaches, as the position of the coach floor must be horizontal at every moment in order to avoid some disturbed motion as the rotation around the horizontal lateral axes. The proposal for the system of axys, the calculus algorithm and the estimation of the correct position of the Diesel engine inside the coach represent the basis of the paper.
