Ivanchuk Y. Methods and tools for mathematical modeling of hydraulic vibrating and vibro-impact machines

The dissertation is devoted to the development and research of an effective generalized methodology for identifying the functioning processes of hydraulic vibrating and vibro-impact machines. As a result of the development of a generalized methodology, the method of graph-analytical determination of the stability region of the pressure pulse generator was first developed. The method of statistical linearization in stochastic mathematical models is developed. Mathematical models of hydraulic vibrating and vibro-impact machines have been developed. A new method for the numerical simulation of hydrodynamic processes is developed. The classification of types of oscillatory systems is developed. A criterion for determining the type of hydraulic vibrating and vibration-shock systems is proposed. Developed generalized methods and tools for computer simulation of the functioning of hydraulic vibrating and vibro-impact machines. An integrated settlement software environment has been developed using separate software systems and client-service technology. A technique has been developed for experimental research of working processes in a hydro-pulse drive, as well as for the technological characteristics of the medium being treated. A design methodology for calculating the drive of vibrating and vibro-impact machines has been developed.
