  • The method of calculating the oval placeholder element three-layer design

    This article presents the basic assumptions and calculation scheme, allowing to obtain an approximate method of calculation of the filler of three-layer structures with a sufficiently large deformability, ie structures, deflections which are comparable to the thickness of the three-layer package as a whole.

    Keywords: deformability, load, filler, load, energy, energy-absorbing element, hinge, travel speed, layer, elasticity

  • Example of calculation of an oval element of a three-layer construction filler

    In this article, we propose a method for determining the reactive load for an element of the oval rod type with a rectangular or square cross-section, in which the diagrams of the moments of external forces and single loads are rectilinear. In this case, integration can be performed analytically

    Keywords: energy-absorbing element, plot, rod, filler, load, beam, hinge, travel speed, layer

  • Energy absorbing panel for seismic protection structures

    Currently actively developing direction of seismic protection, the identified using absorbing screens made in the form of sandwich structures. The present paper presents a design руктивная scheme of energy absorbing panel, which allows you to raise, if used, seismic stability of constructions.

    Keywords: Dynamic loading, uprugoplastichesky deformation, deformation chart, power absorption

  • Method of calculation of power characteristics of belt elastic element

    Currently actively developing direction of seismic protection, the identified using absorbing screens made in the form of sandwich structures with упругопластическими energy-absorbing elements. In this article, on the basis of the conducted research and analysis, the formulas for the calculation of power characteristics of belt elastic element.

  • Calculation of elastic-plastic torsion absorber

    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.

    Keywords: Dynamic loading, uprugoplastichesky deformation, deformation chart, power absorption, tooth strength

  • Rationale for the design features energopoglotiteley seismic structures

    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.
