The research showed that in the study of fluctuations of the car's upright mass the fluctuations of the car's unconstrained mass can be ignored, because the unconstrained mass transmits to the upright mass the vibrations only of high frequency and small amplitude, which impose only some high frequency vibration, close to the sound vibration, and therefore have no effect on the appearance of resonance at the vibration of the upright mass. The practice of calculating vertical oscillations of the car's cushioned mass and not taking into account the track elasticity does not result in errors exceeding 1-3%. Such an error in the results of calculating the oscillations of the car's cushioned mass is quite acceptable for solving the task set in the thesis work. In the article the problem of oscillations of the unrestrained mass of the open rolling stock at asymmetric location of cargo is considered under the assumption that only long irregularities of railroad strings in a vertical plane are considered as a random function of influence from the railroad track.
