Abstract:

The problems of dynamics and stability of hydraulic drives are considered on the example of the fan type working members of the tea-plucking machine "Sakartvelo" chaser. Are derived the design formulae for the angular velocity and acceleration of the shaft of the hydraulic motor as a function of time from the condition of equilibrium stability. Is determined that at selection of a pump and hydraulic motor would be taken into account the characteristics of the fan and the leakage coefficients of hydraulic units.

Keywords: Hydraulic drive; stability; leakage coefficient; agricultural machine.
