The object of this study is the processes of emergence, perception, and
redistribution of loads in the supporting
structure of a 1CC size container with
end walls made of sandwich panels.
To reduce the longitudinal load of
the container under operational modes,
the introduction of sandwich panels into
its design is proposed. This solution is
implemented on the example of its end
walls as the most loaded component of
the body in operation.
The thickness of the sandwich panel
sheet was determined, provided that
the strength in operation is ensured.
Mathematical modeling of dynamic
load of a container with end walls made
of sandwich panels placed on a platform
car during shunting co-impact was carried out. It was established that taking
into account the proposed improvement
makes it possible to reduce the dynamic loads that the container perceives by
10 % compared to the typical structure.
The results were confirmed by computer simulation of the dynamic load of the
container. The models formed within
the framework of the study were verified according to the F-criterion.
The results of calculations for the
strength of the container showed that
the stresses in its structure are 15 %
lower than those in the typical one.
A feature of the findings is that the
proposed improvement of the container
helps improve its strength in operation
by reducing the loads acting on it.
The scope of practical use of the
results is the engineering industry,
namely, railroad transport. At the same
time, the conditions for the practical
application of the research results are
the introduction of energy-absorbing
material as a component of the sandwich panel.
This study will contribute to devising recommendations for designing
modern structures of vehicles of a modular type and for improving the efficiency of the transport industry
