Title of the articleMethods of assessing the ability of holding road enclosure
Abstract.The paper presents a methodology for calculating the energy consumption and dynamic deflection of a road protection and dynamic deflection on the basis of structural mechanics approaches. For one of the private fencing options, a numerical study of the influence of various design solutions to work construction fences, barrier-type car. Presented the results theoretical calculations of fences trough, on the basis of which it is possible to carry out the selection and make recommendations to increase the holding capacity of the structure. With the developed method of calculation in the article and the dynamic power consumption of guardrails and dynamic deflection deflection based approaches structural mechanics we managed to get that basically all of the energy of the car hitting the road fence extinguished by plastic deformation of the extension beams and fencing energy capacity rack bending. The elastic energy intensity of bending plastic power consumption when flattening the beam section type «Wave» and the plastic deformation energy intensity at the bend negligibly small, it means that the calculation can be neglected. They perform a constructive function, but does not protect.
Keywords.road fence, bending, flattening, elongation, desk.
