Dynamic load modelling for tank containers with the frame of circle pipes and structurally improved fittings

Abstract

Higher efficiency of bulked cargo transportation along international transport corridors can be achieved with a resource-saving tank container described in the study. A characteristic feature of a tank container is the use of circle pipes as the carrying elements of the frame. In order to decrease impact loads between fittings of the tank container and fitting stops of the flat wagon at shunting impacts, the authors suggest filling fittings with viscous or viscoelastic materials of dumping or anticorrosive properties. The study also deals with modelling dynamic loading for the suggested tank container. The accelerations obtained were considered in strength calculations for a tank container as components of the dynamic loading. It was determined that the maximum equivalent loads did not exceed the admissible loads. The research will promote designing new-generation tank containers of improved technical, economical and ecological properties, and improve the working efficiency of combined transportation.
