Abstract

The work is devoted to the study of dynamic loads arising in the hydraulic system of the clamping mechanism of a roll of a two-cone unwinder rolls pipe-welding unit 159-529. A mathematical model for the study of dynamic processes in the hydraulic system of clamping a roll, taking into account the wave properties of long hydraulic lines, is proposed. During the implementation of the mathematical model in the Simulink MATLAB environment, a study was made of the operating modes of the hydraulic system of the roll clamp mechanism. As a result of the study, it was shown that in the hydraulic system of the clamping mechanism of a roll of a two-cone unwinder, dynamic loads occur at the end of the return stroke. A procedure for the operation of control valves with a response time of 0.16 seconds is proposed. This allows you to significantly reduce dynamic loads in the hydraulic system of the roll clamping mechanism.
