Description
Summary:On the railway transport network tank-wagons are operated with safety arches, either directly welded to the tank shell, or mounted on a bracket with a base on the shell. In emergency situations the arc can take the role of a tank shell puncher, which will lead to the release of dangerous liquid cargo into the environment. To prevent such damage to the tank the simulation of the conditions for the breakdown of the tank shell was carried out in a nonlinear static formulation in models with and without a safety arc on the bracket. This modeling allows to form a methodology for determining the strength characteristics of tank shells under impact conditions and to implement the protection of structural vulnerabilities in such situations. The mounting option for safety arches with a bracket showed the best results. Therefore, further research to obtain the best strength characteristics of tank boilers is expedient and effective in this particular variant.
