The article studies the structural design scheme of hydro-impulse device for strain hardening parts with a built-in pressure pulse generator. Based on the structural scheme and the timeline duty cycle device, dynamic and mathematical models are developed. In these models a hydraulic section is represented by a visco-elastic fluid model (energy source), composed of instantaneous elastic and dissipative elements (Kelvin-Voigt material).
The article presents the requirements imposed on a vibro-hammer drive with an electrohydraulic control system and the ways to support them. The process of gradual drawdown complex is described, on the basis of which, a simplified dynamic model and its further solver, such as a system of equations, are built. The results of mathematical research are also presented.
