Analysis of the strength of a hopper-type container when transported by a semi-trailer
Abstract
Ensuring sustainable and stable development of the state economy necessitates the introduction into operation of intermodal transport systems. One of the most promising and widespread among them is container transportation. In order to maintain the competitiveness of container transportation, it is important to put into operation modern designs of containers intended for the transportation of a wide range of goods. In this regard, within the framework of the article, the design of a hopper-type container is proposed, which allows to transport bulk materials, as well as cargoes that require protection from atmospheric effects with the possibility of further unloading by gravity under the influence of gravitational properties. The results of the calculation of the strength of the container when loaded on a semi-trailer, as well as during its transportation, are presented. It was established that with the considered load schemes, the strength of the container is ensured. The natural frequencies and shapes of the container's vibrations are determined. The results of the thermal analysis of its design are given. It was established that the strength of the supporting structure of the container is maintained at a temperature of the transported cargo of 96°С. The conducted research will contribute to the creation of multi-functional container designs and increase the efficiency of container transportation.
