Abstract

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
