Higher efficiency of freight transportation can be achieved through the use of a hopper-type container. This paper presents the results of determining the dynamic loading for a container placed on a flat car during shunting impact. It was found that the maximum accelerations to a container in the longitudinal direction were 36.7 m/s2 (3.7g). The value of acceleration obtained was included in the strength calculation for the container. The maximum equivalent stresses of a container were concentrated in the areas where the bottom side rail interacted with the fittings; they were 315.1 MPa, thus they did not exceed the allowable values. The paper presents the results of the strength calculation for a container in the process of stacking. The maximum equivalent stresses in this scheme of loading were 245.3 MPa, which is lower than the allowable values. The authors suggest a lift-off roof on the container for transportation of freight requiring weather protection. The results of the strength calculation for the roof under the longitudinal loads demonstrated that the maximum equivalent stresses in it were 50.2 MPa, which is considerably lower than the allowable values. The research will be valuable for those who develop advanced container structures with better operational efficiency intended for container transportation. [ABSTRACT FROM AUTHOR] |
