In article results of theoretical researches according to smoothing capacity of trunks of the extra-low pressure are resulted. Dependence of length of a spot of contact on its design data, loads and pressure of air is received. It is established, that trunks of the extra-low pressure possess greater smoothing capacity in comparison with other types of trunks, owing to it decreases vibration loading dynamic system.
dynamic system, the highly elastic trunk, ground, mover
