improvement in the maintenance of oneparted railway
wheels towed vehicle, with modern methods of
diagnosis and procedure in order to achieve
satisfactory levels of reliability in operation.
Comprehensive research has shown that the
introduction of this new technological process of
maintaining of the wreath of monoblock wheels,
quality ER7, makes a great technological importance
in improving the maintenance of vital rail vehiclepoint
in our own workshop facilities of railway
direction. The study also confirmed that, the
implementation of this, an entirely new technological
maintenance procedures wreath monoblock wheel, is
applicable and feasible technical and technical process
for the existing workshop facilities to deal with the
problem of maintenance of railway vehicles without
significant investment.
Surveys were conducted in stages. First in detail are
implemented the theoretical research achievements,
based on the study and application of modern
techniques and technologies, made to maintain the
vital elements of railway technical
systems. Implementation of this theoretical study is
produced by the realistic sound and comprehensive
scientific foundation, which allowed reasonable access
to experimental, and also exploitation research. This
comprehensive scientific research process, resulted a
satisfactory scientific research findings, which for sure
will create a sound basis for scientific discussion and
also access to practical use by the railway companies
of our country.
The whole process of dissertation research subjects is
based on the latest achievements of scientific
knowledge in mechanical engineering studies such as:
the technology of metal processing, steel production
technology, metal mechanics, strength of materials,
welding metallurgy, physics, chemistry, etc..
Experimental research and exploitation, were
accompanied by modern diagnostic methods and
procedures, merit-making for the adoption of scientific
decisions and evidence at the level of quality and
reliability. It is shown that besides the methods of
fracture of metals and mechanics metallurgy standard
test methods, the introduction of modern ultrasonic
diagnostic techniques and technologies in the process
of diagnosing vital railway vehicle, as a monoblock
points, largely provides a high degree of reliability by
providing a significant contribution to this research for
confirming technological feasibility of the process.
Technological process of wreath restoring of
monoblock wheels, quality ER7, which are subjected
to the mechanical process of wear and combinated
static and dynamic loads, in the process od
