METHODS OF PROCESSING THE RESULTS OF HYDRAULIC EXPERIMENT

Posted in 2017, ENGINEERING, Issue № 3(57) March 2017 | 0 comments

This article describes the technique of processing a natural experiment. The article provides recommendations based on current regulations in this part, the use of statistical methods of processing of experimental data. Examples for the calculation of accuracy of measurement results the most common in experimental studies of hydraulic parameters such as flow, pressure and speed. From the correctness of processing of the experimental values is their reliability and the possibility of their further use.

EXPERIMENTAL RESEARCH OF CATERPILLAR TRACTOR’S SPEED INFLUENCE ON SOIL COMPACTION

Posted in 2017, ENGINEERING, Issue № 3(57) March 2017 | 0 comments

The article discusses the caterpillar tractor’s impact on the soil. The paper proposes a method of determining the normal pressure and tension in the soil at different depths. Pressure sensors were installed to a depth of 0,2 m, 0,5 m, 0,8 m. Measurements of pressure were carried out when the tractor is idling and with a hook load of 80 kN with a point of application at a height of 0,4 m from the reference surface. Experimental values of the ground pressure of the tractor T-170М1.03-55 depending on speed and traction loads. Plot the normal pressure has two local extremum in the zones of the first and sixth track rollers,…282,1 is 220 kPa. While tractor is driving without traction load the highest pressure is concentrated in the area of the front road wheels, a significant excess pressures under the first track roller should be attributed to the forward displacement of the tractor’s pressure center. The increase in speed from 0,88 to 2,41 m/s of the tractor leads to a reduction in the maximum pressure by 5-10%.

DEVELOPMENT OF A MODEL OF THE TECHNOLOGICAL SCHEME OF CIRCULATING WATER OF METALLURGICAL ENTERPRISES WITH THE USE OF THE SOFTWARE ASPEN PLUS

Posted in 2017, ENGINEERING, Issue № 2(56) February 2017 | 0 comments

In this paper, we have considered the importance of recycled water in industrial steel mills and the main problems that arise are scale, biofouling and corrosion. The importance of process modeling has been discussed and the model of water correction treatment of circulating water supply has been propose. The model of a technological scheme of recycling water supply system has been developed and the analysis of its work has been carried out. For the simulation the data from commercial operation of a water circulation system and the results of material and heat balance to determine the entrainment of water in the cooling tower due to evaporation during cooling have been used.

INFLUENCE OF WHEAT GRAIN STRUCTURAL-MECHANICAL PROPERTIES ON ITS TECHNOLOGICAL QUALITY

Posted in 2017, ENGINEERING, Issue № 2(56) February 2017 | 0 comments

The article examines the questions of the purpose for wheat grain flour depending on the dispersion degree. There are the differences in the formation of grinding grain batches in accordance with its structural and mechanical properties in article. It is revealed significant relationships indicator of grain hardness and rheological properties of the dough. It is determined the nature of the relationship developed by the regression equation used to predict the technological properties of grain hardness. We show the importance of assessing the structural and mechanical characteristics in the processing of wheat grain production.

EXPERIMENTAL STUDIES OF SELF-SIMILAR SYSTEMS IN WATER LIQUID CHROMATOGRAPHY

Posted in 2017, ENGINEERING, Issue № 2(56) February 2017 | 0 comments

This article is devoted to the study of memory of water due to changes in the structure of [1] and the possibility of onward transmission of these changes to other samples of water. To implement these conditions in the structure of water self-similar systems are needed. In order to find the similarity phenomenon itself were conducted investigating the dynamic characteristics of the output time of the aqueous medium peak fractions by high pressure liquid chromatography, HPLC method is a direct method that can separate the structural elements of size and charge. In order to study the properties of such cells spontaneously formed in the volume we have chosen for the study of highly pure water, which is called «super-Q».

ENGINES FOR UNMANNED AERIAL VEHICLES

Posted in 2017, ENGINEERING, Issue № 2(56) February 2017 | 0 comments

This article explains the advantage of using electric motors for unmanned aerial vehicles before the use of internal combustion engines. The article also identifies the features of construction of the propulsion system consisting of electric motors for unmanned aerial vehicles, operating at altitudes of about eighteen thousand meters, and discusses the advantages and disadvantages of brushless motors, which today are most often used on unmanned aerial vehicles.
