Abstract: Using finite element method the estimate of influence rigidity of the framework elements of tram car bogie on its own frequency and shapes is performed. The possibility of evaluation of the frequency range, in which the elements of the frame of a bogie can be considered as absolutely rigid, is shown.

Keywords: tram car bogie, natural frequencies and shapes, vibration isolation, absolutely rigid body.
