Currently most used energy absorbers can be represented classic spring-damper scheme in which the binding is the presence of the elastic work item and damper. Applied to seysmoudarnomu works best security systems installations are systems that do not have elastic elements. For hard metals, which are material for the work items absorber characterized by the appearance of a tooth during the deformation strength. For the calculation of the power characteristics of the work item should be modeled phenomenon associated with the formation of the yield drop. Modeling of the phenomenon of this article.

Currently actively promote seismic associated with the use of special devices, so-called energopoglotiteley. This paper shows that the design energopoglotiteley advisable to make so that the work item had torsional strain. These EPA bdut have maximum energy absorption with minimal weight. Designs of EPA.
