The object of this study is the processes of
perception and redistribution of vertical loads
in the structure of a container with a floor made
of sandwich panels under operational modes.
To ensure the strength of the container, as
well as the safety of the cargo transported in it,
it is proposed to design a floor based on sandwich panels. It is assumed that each of these
panels is made of two metal sheets in a layer
between which an energy-absorbing material
is placed. Given the presence of energy-absorbing material in the structure of the sandwich
panel, the vertical dynamic loads acting on the
cargo container during its transportation will
be reduced.
To substantiate the proposed solution,
mathematical modeling of the vertical load on
the container during its transportation by a
flat wagon was carried out. It is found that the
accelerations acting on the container of the
improved design are 5.7 % lower than those
acting on the container of standard design.
The calculation of the strength of the container was carried out under operational
schemes of its loads. It has been established
that the strength of the container is ensured.
A special feature of the results is that
the reduction of the load on the container is
achieved not by strengthening its structure but
by introducing flexible connections into it.
The field of practical application of the
results is railroad transport. The conditions
for the practical use of the findings are the use
of energy-absorbing material in the structure
of sandwich panels that form the floor of the
container.
The results of the research will contribute
to improving the strength of containers under
operating conditions, the safety of the cargo
transported in them, as well as increasing the
efficiency of the functioning of container transportation
