The article describes the method of determining the list of rational diagnostic parameters of the brake system of a vehicle using the theory of probability and mathematical statistics. The problems determining the statistical probabilities of failures on objects considered a run; mathematical models (regression dependence) the probability of failure of run; A statistical evaluation of the significance of the coefficients of regression models; verification has been made on the adequacy of the regression models; the probabilities of possible states of objects. On the basis of the construction and analysis of structural- effect model brake system information and calculates the importance of each monitored parameter using the notion of information entropy, determine the parameters to be diagnostic, and builds a matrix condition of brake systems for non-destructive testing, in order to move on maintenance and repair of the actual state
Potato has been and remains one of the five world's
most important crops. For nearly two hundred years
potato in Russia is the "second bread". This is one of
the so-called social products. Over the past 20 - 25
years of potato farming in our country, there have been
significant changes, both positive and negative. Today,
potatoes are grown in different soil and climatic
conditions in more than one hundred countries around
the world, including the desert oasis and beyond the
polar circle. Potato cultivation Center recently has
moved to Asia. In our time, the leaders of potato
production are China, Russia, India, the US and
Ukraine. Over the past few decades the number of
produced potatoes has increased by 41% and the area under potato planting only 9.5%. From the above data
it is clear that the world potato economy in recent
years has got significant changes, indicating that the
timeliness and relevance of the material in this article
is true
This article discusses the results of the studies of the faculty and the staff of Ryazan State Agrotechnological University named after P.A. Kostychev confirmed with RF patents
The article presents native and foreign bench-top
and board methods to test the automobile break
systems. One can find information about some
native trailer-break stands. We have analyzed their
advantages and drawbacks such as low information
capacity, high diagnostics processing time, low
quality of regulation and maintenance operations
due to big influence of the operator’s experience,
his knowledge and individual characteristics, and
great instability of manual test modes on the results
of the investigations. To remove these shortcomings
they have had some experiments at MADI in order
to develop the module to the brake qualities stand.
When using it one can have automatic diagnoses
and flow chart is presented in the article. Due to the
existing vehicles’ state inspection mode and
diagnostic means in our country there appeared new
stands for brakes control. One can attribute to these
devices a range of brake qualities stands developed
and produced at Novgorod plant GARO. These are
STS-3, STS-10 and STO series stands for cars,
trucks, buses and micro-buses. The article also
presents some foreign stands used in Russia such as
universal brake stands STM by META firm, the
break stand IW7 Eurosystem by MAHARUSSIA
firm. We have presented in the article the results of
the analysis of simple and complicated board means
of diagnosis as “Eftor-2”, “Effect”
In agriculture the issue of enhancing the
efficiency of operation of internal combustion
engines (ICE), reducing the costs of
maintenance (TO) and repairing (TP) fuel
supply apparatus (TA) using the improvement
of methods and means of diagnosis is a topical
in connection with the aging rolling stock
farming and lack of investment. Analysis of the
known TA diesel engine vehicles systems
showed that the most widespread system is the
divided type with multiplunger high pressure
fuel pump (fuel pump), while the methods of its
diagnosing are laborious, they require partial
disassembly and have insufficient accuracy.
The mathematical models that characterize the
work of a high-pressure fuel pump (fuel pump)
use a large number of parameters that
significantly affect the quality of dynamics of
the change of pressure values of diesel fuel.
However, in the materials of previously
published articles there were no issues
considered assessing the extent of the
quantitative impact, performance and features
change in the sensitivity settings of the
mathematical models on the simulation results,
there are no recommendations on the degree of
sensitivity and importance of each of the
parameters. For a more accurate diagnosis of
the fuel supply apparatus of a diesel engine it is
advisable to use several methods of diagnosing.
The article substantiates development of a
mathematical model of a high-pressure fuel
pump based on the analysis of modern methods
of diagnosing of fuel equipment for autotractor
diesel engines
The development of agricultural production inevitably
entails an increasing volume of traffic and a turnover of
goods. Therefore, the issues of increasing transport
efficiency, reducing the price of transportations and
improving productivity acquire great importance.
In most cases, supersize dump trucks used for the
transport of agricultural production have much more than 6 tons axle load. Thus, these cars need to have
roads with improved surface to each field, which
undoubtedly is a significant drawback. Because of the
extra movements of harvester dump trucks on the
turning strip at the end of the field, it increases expenses
of damage and loss of crops and the arrival of heavy
machinery in the field leading to soil compaction, that
in the end affects the future crop. Transportation of
agricultural commodities is most effective when the car
arrives directly to the harvester machinery. Such
vehicles must have sufficient abilities and capacity of
the body comparable with the volume of a combine
hopper and has no significant impact on soil sealing.
With this method, harvesters do not make extra
movements and are not idle. Basic requirements for
vehicles used in the harvesting potatoes, are in a more
productive use due to increasing the capacity and
reducing downtime when loading or unloading and
minimizing the level of damage to other tubers. For the
transportation of agricultural products there is a
different transport technology, which either do not fully
meets the requirements of transportation of highly
fragile product, or has a significant cost. Therefore, we
require a specially equipped vehicle bodies, with a
competitive ability in the range acceptable to the
Russian Federation. As one of the innovative
developments, this article proposes a tipper body of the
vehicle for transportation of highly fragile agricultural
products. The proposed design solution for the tipper
ensures a uniform unloading of transported products
from the vehicle body and prevents arching issues
An integral part of technological process for the cultivation of agricultural crop is the transportation issues. For their execution, we require significant energy and labor costs. The statistics show that the proportion of expenses for transportation of goods in agriculture reaches 25-40% of the total costs for ready-to-sale production, when the proportion of farm tractor transportations reaches 60% of the total. Thus, there are considerable losses of production, reaching in separate cases up to 50%. They are especially great in the harvesting and post-harvest cycles of crop production which is connected with crop damage during transportation. Large losses of fruit and vegetable products when transporting might be connected with their mechanical damage level during loading, unloading and transportation. This causes the urgency of the problem of preservation when transporting fruit and vegetables. One of the prior national issues is "... the development of directions to improve road transport maintenance with the aim of improving the quality of the transport process, which includes increasing commercial speed of freight flows by 2-3 times, increase productivity and profitability of road transport systems by 2-3 times, reducing the environmental load on nature by 20% ... " and others mentioned in the "Transport Strategy of Russia until 2020"
Material and technical resources form a large part of the
costs in agricultural production and determine the level
of intensity of agriculture, productivity and
competitiveness of the industry. The most important
role in agricultural production is played by transport
operation, from productivity and quality of which
directly depends the volume and the grade of final
products. More preferable is tractor transport,
particularly for on-farm transport, taking into account
the impact of navigation systems on the ground.
Continuous growth in the saturation of tractors carried
out around the world, improves the performance of
tractor transport aggregate by increasing their capacity and speed, either on the road or in the field. However, if
you increase the saturation of tractors, it encounters
problems related to the deterioration of the
controllability of the tractor and transport unit. The
reduced controllability leads to an increase of damage to
transported agricultural products owing to increased
oscillatory processes in the system of "road – trailer –
tractor – operator" when driving on-farm trails,
deteriorating the smoothness and braking properties.
Especially sharp these questions relate to transportation
of easy-to-damage agricultural products at farm
transportation. The feature of data traffic lies in the
sharp drop in grade products (products receive
numerous mechanical damages, deteriorating its quality,
and lose marketability and accordingly reduced its cost).
Influence on fruit and vegetable products of unfavorable
factors can lead not only to a dramatic loss of quality at
the time of transportation, but also reduce the resistance
during further storage. To solve the problems emerging
when increasing the saturation of tractors, we have
proposed devices, allowing reducing negative impact on
the production of elevated oscillatory processes, to
increase the permeability and straightness of movement
of tractor-transport unit
