- Abstract
The article deals with considerations regarding the geometric filtering effect of the bounce and pitch movements derived from a railway vehicle movement on a track with irregularities. The cases in which the geometric filtering effect of the bounce and pitch movements in a bogie are presented and so is for a bogie-based vehicle, plus the corresponding filtering frequencies. The characteristics of the geometric filtering of the symmetrical and antisymmetrical movements of bounce and pitch are examined for the plans of axles in a vehicle. The analysis of the geometric filtering effect influence upon the behavior of vertical vibrations proves the selective nature of the geometric filtering depending on the velocity, the position along the carbody and the vehicle natural vibration modes.
