Abstract

The paper presents the method of designing equipment for protection the hydraulic system, and particularly hydraulic machines, against dynamic loads. The example of such machine is a powered mining support. A support must work in the conditions related with rock crumps what causes large and quick energy releasing. The designing process bases on the integrated approach what let taking into consideration all needed elements of this process [1,. Each of the elements of the design process could be an independent design agent which could find its solution both in CAD technique and other modeling tools [3,4]. Moreover in the paper is presented the results of computer analysis of the presented solution. This design solution bases on the application, in the protected hydraulic system, two complementary valves: the quick-release valve and the large-caliber one. Analysis of this valve system allow to state that this technical solution should protect a hydraulic system against dynamic loads of any energy.
