Purpose

Investigation of elastic-dissipative stabilization of dynamic processes of hydropulse systems of mining machines.

Methodology

The studies were carried out through analyzing effective elastic- dissipative connections of elements of structures. Parameters are calculated by methods of finite and differential differences with conducting of experimental researches.

Findings

The results of investigations of the dynamic processes of the functioning of the hydropulse system and means of reducing the impact on the base machine that are given in the article. Effective elastic-dissipative connections of elements of structures that influence the stabilization of dynamic processes are offered. Their parameters are calculated by methods of finite and differential differences with conducting of experimental researches. Connections: the waveguide reduces the dynamic factor by 25 ... 30%; heterogeneous lyophobic system, which provides an increase in the decrement of the damping vibrations of 1,4 ... 1,95.

Keywords: stabilization, stiffness, dissipation, hydraulic hammer, waveguide, heterogeneous lyophobic system
