Conclusions

  1. 1.

    A model of a hydraulic impact machine makes it possible to solve comprehensively the problem of choice of the parameters of the main component elements: drive, impact mechanism, and control unit.

  2. 2.

    With various combinations of coefficients determining the machine parameters, three regimes can be achieved: cyclic, pseudocyclic, and acyclic. The cyclic regime is most efficient and allows one to maximize impact power. As machine parameters deviate from installed settings, the regime becomes pseudocyclic or acyclic.

  3. 3.

    The machine parameters that have been found in the study determine unequivocally the installed power capacity of the drive and its redistribution between the phases of the impact mechanism.

  4. 4.

    Each regime can be controlled by means of the third derivative of the time function of the striker's motion. Depending on the type of feedback, three diagrams of the control action variation are obtained, which are determined unequivocally by the parameters of the impact mechanism and the drive.
