Dynamic and mathematical models of hydro-impulsive device for strain hardening of parts with an built-in generator of pressure impulse
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).
