Abstract

The relevance of the research is that the development of technology requires the creation of strong, reliable, durable structures that are used in many mechanisms. Therefore, the main goal of the work is to study the quasi-static stability of the ribbed shell, which is affected by the mobile load. For a full study, the work was based on methods of analysis, review, modeling, experiment, comparison. All of them allowed to decompose the investigated problem into elements and accordingly study each of them. As a result, the authors in a quasistatic formulation solved the problem of the stability of a shallow shell with a discrete arrangement of stiffeners under the action of a moving linear radial load. In this case, the spectrum of the critical velocities of the load is determined. The work is of practical importance in the construction of designs of lethal devices, for which a stable ribbed shell is used.
