Study of Strength of Open Wagon with Tank Containers Under Operational Modes

A removable module design is proposed to enable the use of open wagons for container transport. It acts as an intermediate adapter between an open wagon body and a tank container, ensuring the possibility of their reliable interaction. The dynamic loading of its structure was determined to substantiate the proposed scheme of tank container transport on an open wagon. A mathematical model characterizing the longitudinal load of a tank container placed on an open wagon was developed for this purpose. The determined accelerations acting on the tank container were considered when studying its strength. It was established that, considering the proposed fastening scheme, the maximum stresses occurring in the tank container structure are lower by 21.8% than the permissible ones. Therefore, the strength of the tank container is ensured. Accelerations acting on an open wagon body and a tank container were determined and considered when studying their strength. It was found that the maximum stresses occurring in the open wagon body and the tank container, considering the proposed fastening scheme, are lower than the permissible ones. Therefore, the strength of their structures is ensured. The research conducted will contribute to increasing the efficiency of tank container transport by rail and, therefore, container transportation in general.
