This article is devoted to the development of an automated system for the theoretical study of hydrodynamic processes occurring in pressure generators of hydraulic vibrating and vibro-impact machines. Intensification of various technological processes in industry and agriculture requires the use of advanced technologies - vibrating and vibro-impact technological equipment. Effective modes of operation hydraulic vibrating and vibro-impact machines are determined by special generators of pressure pulses - valve-pulsers. To study the operating modes of vibrating and vibro-impact machines at various technological parameters, an automated system of mathematical simulation of a hydroimpulse drive has been developed. The method of final volumes in the CFD-program was used to determine the main dependencies of the working parameters of pressure generators for vibrating and vibro-impact machines. The results of automated modeling allowed us to evaluate the efficiency of the developed designs of pressure pulse generators at various operating modes of hydraulic vibrating and vibro-impact technological equipment.
