Fabrichniy D.Y., Tolengutova M. M., Fabrichniy Y.F. Automatic adjustment systems for hydraulic impact machines according to the tool load

Automatic adjustment systems for hydraulic impact machines according to the tool load

Fabrichniy D.Y., Tolengutova M. M., Fabrichniy Y.F.

Hydraulic impact machines are widely used in mining, construction and other industries for rock and man-made material destruction, for shaping objects and other manufacturing operations. Nowadays, there are a lot of hydraulic machines distinguished by layouts, designs and options. However, their common feature is the lack of automatic adjustment systems for operating parameters depending on the tool load. The problem is to increase hydraulic machine performance at the expense of the input power rational consumption as well as to enhance the efficiency. The paper presents the search result of systems capable of solving the problem. It is shown that hydraulic fluid flow controls and the striker travel value will lead to the automatic adjustment of both impact frequency and single-impact energy of a machine depending on the tool load.

Keywords: hydraulic blow device, hydrodrummer, working liquid, energy of single blow, frequency of blows, a loading of the tool, automatic control.

Lazutkin S.L., Lazutkina N.A. The research of the static-dynamic well formation process

The research of the static-dynamic well formation process

Lazutkin S.L., Lazutkina N.A.

The paper deals with the study of the interaction of the working body with the ground in order to achieve the borehole wall maximum density, which can be provided by a certain ratio of the actual speed of axial feed and the impact device output parameters. The idea of the scientific research is that after the impact the ground brought into the state of partial thixotropic softening should be statically deformed. This leads to the fact that the total plastic deformation range increases significantly, which will result in the ground density growth. Since the thixotropic softening process is limited in time and space, it is necessary to determine the relationship of the machine input parameters and rational values of the static effects, showing the ratio of static and dynamic soil loading. The results of laboratory experiments on the well formation modes study are given.

Keywords: the drainage cavity in the ground, soil density, static-dynamic interaction, indicator static influence.

Ermoshenko Y.V., Bolshakov R.S., Kaimov E.V. Dynamic response in the vibration-protection system assessment

Dynamic response in the vibration-protection system assessment

Ermoshenko Y.V., Bolshakov R.S., Kaimov E.V.

The paper considers dynamic response identification method in mechanical vibration systems. Dynamic reactions between inertial-mass and connecting elements (springs and dampers) as well as reactions in contacts with bearing surfaces are determined on the basis of obtaining reduced rigidities. These parameters are determined during the transformation of structural models of initial design schemes. The approach under discussion is based on structural concept of mechanical vibration systems. They are transformed into corresponding structural schemes of automatic control systems. When you select an object for the constraint force calculation as the second-order integrator which corresponds to the object to protect in vibration-proof systems, for example, the feedback physically corresponds to the dynamic response. The examples are given. The technique for performing required changes and obtaining analytical relations for dynamic connection response determination is developed.

Keywords: method of definition of dynamic reactions at vibration influences, vibroprotection systems, transfer functions.

Sharapov R.V. Conformity algorithm for exogenous processes monitoring data

Conformity algorithm for exogenous processes monitoring data

Sharapov R.V.

The paper deals with conformity of exogenous processes monitoring data obtained from different sources. To provide sharing data with different accuracy and measurement error, an algorithm for its conformity is present-ed. The algorithm involves bringing data to a single measurement unit. Data with varying accuracy is brought to single accuracy and order. Accuracy is determined by taking into account the measurement interval. For con-formal processing data, having different error, a three-item combination of «value, accuracy, measuring inter-val» is applied. Error value can significantly change the measurement data. For this reason, when calculating the trend lines (process dynamics) from various sources data, it is necessary to perform the estimation based on the three values rather than on a specific value.

Keywords: exogenous processes, monitoring, data, data processing, error, matching.

Sharapov R.V. On the conformity of monitoring data obtained from various sources

On the conformity of monitoring data obtained from various sources

Sharapov R.V.

The paper deals with the issues of processing data obtained from different sources. This data formats are different and can be received by means of different devices using various techniques. Furthermore, data may have different accuracy and measurement error. This complicates their sharing and can lead to significant errors. That is why, it is advisable to apply three-item combinations of «value, error, measurement interval», converting and bringing the combinations to common measurement units, if necessary, instead of using direct indicator readings taken from one source or another. This solution enables us to provide sufficient adequacy of data, collected from various sources, to the practical situation. In addition, the measurement error record enables us to assess the processes dynamics more accurately. So, you can filter value instability in the error zone and identify really significant changes.

Keywords: exogenous processes, monitoring, data, data processing, error, information source.

Effectiveness evaluation of automated environmental groundwater monitoring systemal

Dorofeev N.V., Orekhov A.A., Romanov R.V.

The paper presents the effectiveness dependence of the long-term automated environmental groundwater monitoring system, based on the aeration zone geoelectric monitoring method as well as on the number of contactless transformer sensors and the distance between them. The equipment costs and the area occupied by the system are considered as well. The basic criteria for evaluating the automated control and monitoring system effectiveness are described. The choice of the statistical criterion for evaluating the effectiveness of similar systems as a basic one is reasoned. According to the results, the optimum number of contactless transformer sensors in the environmental groundwater monitoring system is determined to come at eight. The optimal distance between the sensors is specified as 30 meters. In accordance with these parameters, the system efficiency formula is found. The efficiency calculation was carried out for the multi-electrode setup.

Keywords: groundwater monitoring system, monitoring system, geo-ecology, geo-ecological monitoring, unsaturated zone.
