Abstract
The paper presents a version of the improved string cutting installation for forming bricks with two hydraulic drives. A mathematical model of the movement of the traverse and the carriage of the installation, which require synchronous actions in the process of work, has been compiled. The dependence of the total force of the technological load and friction acting on the traverse on the movement parameters and tool geometry was obtained experimentally. The obtained dependence was used in the development of a mathematical model, represented by a system of nonlinear differential equations that were solved by the Rosenbrock method. A complex criterion for evaluating the efficiency of the automatic installation was formed and the values of the structural parameters of hydraulic drives were found, in which the errors of the geometric dimensions of the products and the power consumption will be minimal, and the productivity of the installation will be maximal.
