Simulation of the hydraulic system of a device with self-adaptation by power and kinematic parameters on the working body

Abstract

At present, Russia has adopted a course towards the creation of intelligent machines and equipment. This also applies to mobile technological machines for road construction and municipal purposes, the difficult operating conditions of which and the complexity of the proposed technical solutions hinder the implementation of this project in practice. Therefore, the design and creation of executive devices with a self-adaptation function for this class of technology is an urgent task. Materials and methods. A device with a hydraulic drive function with self-adaptation to load and coordination of kinematic and power parameters of the main movement and feed movement of the working body of a rock drilling rig is presented. For research and design of the device based on the methods of mathematical modeling of the hydraulic drive and adaptive systems, its mathematical model is proposed. Discussion and conclusion. The mathematical model presented in the article shows the fundamental possibility of the proposed device for implementing the principle of self-adaptation in terms of load under external and internal disturbing influences during its operation.
