Review article

The paper deals with the problem of simulating controlling oscillations processes in the vibration construction machines by using hydraulic shock absorbers. Most vibration construction machines operate in super-resonance oscillation mode. In periods of acceleration and deceleration of the vibration motion, there occurs resonance, namely, a sharp increase in speed and amplitude of the oscillations. Resonance oscillations adversely affect the operation of the machines due to increased dynamic loads reducing the resource and cause increased noise harming the health of the operator. There exist many technical solutions for damping resonant oscillations in machines. According to the author`s opinion, one of the most successful and proven in practice techniques is the use of hydro-pneumatic shock absorbers, the coefficient of resistance of which is proportional to the velocity of oscillations.
