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
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”
Material and technical resources form the bulk of the
cost in the production of agricultural products and
determine the level of intensity of agricultural
development, productivity and competitiveness of the
industry. The most important role in agricultural
production has been given to transport operation, as the
performance and the quality of the implementation of
which depends directly on the amount and the grade of
the products. On intraeconomic transportation in the
APC RF, along with the car we widely use tractor
trucks. Unfortunately, in most cases for the
transportation of agricultural goods we use supersize
trucks, including construction purposes, with a high
axle loading. These vehicles need roads with improved
coating to each field. Here we may note substantial
shortcomings of transportation. Because of the
unnecessary displacements from combines to dump
trucks to the end of the field, the costs and the losses are increasing and the arrival of heavy machinery in the
field leads to soil compaction, which ultimately affects
the future harvest. The successful implementation of
agricultural work is strongly associated with the timely
and volume movement of a variety of materials, such as
animal feed, fertilizers, construction, and other loads. A
lot of these works needs roads; nevertheless, the quality
of agricultural roads and field work significantly affects
the timely and high-quality forage. Thus an important
part of any machinery tractor fleet of agricultural
production is taken by the presence of modern cars,
tractor-trailers and semi-trailers. 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. To address emerging when increasing the
saturation of tractors problems, 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
The article presents a technical diagnostics of a car as a complex of goals and tasks connected with
trouble-shooting of mechanisms and systems in
order to eliminate them. We have considered the
stages of computer diagnostics of different
automobile systems such as diagnosing the engine,
the brake system, steering and suspension. We have
analyzed their components, the ways of troubleshooting
and elimination recommendations. The
article presents the main troubles transferred from
the electronic control unit. The article also presents
the stages of diagnosing the engine including
external examination, listening to abnormal noises,
checking the operating fluids and the engine
management system, diagnosing the basic engine
systems and checking the cylinders being filled.
The article contains the list of main troubles and
their reasons. One can also see diagnosing the brake
system, its defects and remedies. The article
presents diagnostics and repair of the suspender and
graphics describing the check of the dismantled
shock strut at the stand and tests of the shock strut
without being dismantled. We have analyzed
computer diagnostics and the problems it solves
The article presents the methods of efficient monitoring rate of the mobile agricultural equipment brake system based on the usage of methods of the theory of relativity. We have considered the methods of the brake gear monitoring rate according to the acceptable level of reliability, to the technical index and change logic of the technical parameters state and economic-probabilistic method. From the above-stated one can see, first, that diagnosing usage is the development of maintenance preventive strategy. Second, its practicability and the ways of realization are determined by technical and economic calculations
The article presents the way to identify the mobile agricultural equipment technical status control perio-dicity based on the comparison of its defect-free per-formance given probability with its calculated value in order to decrease significantly the efforts to estimate control periodicity and increase the results authenticity at the expense of mobile agricultural equipment prob-able characteristics calculation
