The new ways of decision of problem of reliability of cutting equipment taking into account a difficult situation, which was folded in Ukraine for today, are described in the article. Cutting equipment, repair, renewal, refuse, harvesting, damage, chaindrive.
The algorithm of estimation of probability of faultless work of technical objects is offered in future moments of time. Polinomial canonical decomposition of casual sequence of change of values of the controlled parameter is fixed in basis of algorithm.
A construction is offered aquatic to the pump that includes the permanent occasion of pump and ventilator depending on the temperature of engine. It allows to accelerate warming up of engine, that results in the considerable decline of wear of engine, that takes place at a mionectic temperature.
Assignment number of failures of structural element precast sectional light metal structures. This article discusses the process of functioning of the element of light metal structures Considering that the time to failure element in the process is a random variable X with the assignment F , and the lifetime of the structure as a whole is a random variable Y with the assignment G .
A method and results of experimental researches of amplitude and duration of impulses of pressure by a waveguide sensor at high-voltage impulsive digits in different environments at high (up to 40 MPa) hydrostatical pressure is resulted
Technique of calculation of the third and fourth virial coefficients of non-ideal gas has been represented which is applicable for different types of interaction potential function. The values of the coefficients for the Lennard-Jones (12-6) potential and the Morse potential have been computed in wide range of temperatures.
In the article the analysis of educational theory and practice, given the opportunity to identify the main methods and techniques of a problem in learning tasks and problem approach combining with other methodological approaches.
The article deals with the economic study to determine the efficiency of processing of agricultural products for export is the biodiesel. The strategy of production and export of biodiesel is a promising direction.
The basic problems of the current state of mechanization selection of vegetable seeds and melon crops. The main results of determining the economic efficiency of the complex machinery of the additional allocation of seeds and seed mass of technological refinement of melon and cucumber.
The article is devoted to research features of using of nanotechnology of cleaning up oily water by the way of forming organized environment in the system of “oily water - coalescing sorbent, modified polymeric cationic surfactant” at the surface of the sorbent of coalescing type.
Offered, instead of the screw pressing, to apply innovative technology, using gravity forces for the substantial decline of expenses at making of vegetable butter from seed. Two variants of decision of this problem are examined: with the use of existent equipment and without him. Almost complete automation of pressing process control is thus foreseen, i.e. a minimum of influence on him human factor.
In the article theoretical generalization and new methods is resulted decision of scientific problem which appears in development of scientific and technical bases of providing of reliability of combine harvesters by the improvement of the system of their technical service. The new decision of the put task was found by the experimental addition and confirmation in determination of basic parameters...
The technique of pilot studies of technological process of an rolling of rope sheaves by means of the device with a maple roller is described. Results of pilot studies during that, the method of an abrupt ascension, found out optimum design and kinematic parameters of the device are given.
The usefulness of the conversion of bioethanol by use of the waste heat of gas turbine engine is proved. The scheme of the test bench for experimental studies of processes of thermochemical conversion by heat recovery of exhaust gas turbine engine is given.
The article deals with personal educational environment as a distance education of future professionals in the universities. Describes the concept of distance education and distance learning technologies, the concept of personalized learning environment. Also in the article outlines the features of distance learning technologies, the structure of the personal learning environment, ways to present...
In article two technologies of hardening of metals and alloys are presented: volume hardening of metal preparations in the course of their hardening from a liquid state in firm, superficial hardening of details by means of an obkatyvaniye their rollers. The hypothesis of the mechanism of crushing macro – and metal microstructures is described at electrohydropulse influence – creation of the actual...
