The article describes the modeling process of the
heating system operation of a livestock-breeding
complex. It presents graphs reflecting the influence of
technological parameters of heat supply system of
cattle-breeding complex with a catalytic combustion
device on the parameters of energy efficiency of the
system and the parameters characterizing the stability
of the temperature conditions in the livestock sector
We have presented technical solutions of an energy
supplying complex of apiary based on a solar plant,
which ensure its functioning in the winter. Various
aspects of the influence of the snow cover on the
functioning of the complex are considered in the
article. The favorable effect of the snow cover includes
increasing the diffuse insolation, improving the
thermal insulation of the building for placement of
bees, which protects bee families from fluctuating
external temperature. The negative effect of the snow
cover includes adherence of snow to the receiving
surfaces of solar energy converters, which can lead to
decreasing the efficiency of using of photovoltaic
modules and solar collectors. Both active and passive
methods of combating snow sticking are suggested in
article. Passive methods include installation of solar
energy converters at an angle close to 90°, as well as
their placement on the windward side. The simulation
of the functioning of the complex based on a solar
plant was conducted for climatic conditions of the
Republic of Mari El (the time interval – from 14
October to 14 April, a photovoltaic module area – 1,3
m
2
with installation angles of 72˚ and 88˚). Because of
the simulation, we obtained graphs of the changing the
power of the photovoltaic module. Active methods
include air injection onto the receiving surfaces of
solar energy converters and using of heating elements
In the article, we have presented the technical and the technological aspects of the design and the construction of forestry mounted equipment proposed criteria for study and assessment of the drive system of a mounted Gripping-cuts off device for tractors of small pulling classes
The article presents the original study material designed to determine the influence of soil properties on the cross rate of the transport system. These data allow us to determine the efficiency changes compositions transport system for transporting long cargo
The article presents the description of the method and the results of the experimental research of loading of driving mechanism of felling head of a forest machine
During the study, the authors have solved the problem
of determining the minimum number of operations by
optimizing fillability of a claw-shearing device with
trees. Sufficient optimality conditions have been
obtained. The numerical method for solving the
optimization problem was developed. We have also
performed a numerical experiment
The article presents the approach to modeling of microprofile felling areas as the bearing surface of harvesting machines and is an example of the model obtained in the study of the behavior of wheeled vehicle on uneven support surface
The article presents the mathematical model for
determining the temperature after passing trough
nozzles of press-granulator, which allows to take
into account heat loss through the exterior surface
The article presents investigations of engine oil with
the addition of special additives and reactions of the
composition in the process of friction on the metal
surface, simulating the boundary and hydrodynamic
friction
The article discusses the development process for preparing an extract of lichens on the basis of use of low productivity of natural biogeocenosis using adaptive modular complex harvesting and processing of lichens for more effective use of them
