FEATURES OF STRUCTURES OF ROAD MOBILE FRONTAL BARRIERS AND CALCULATIONS IN DESIGN ANALYS
Abstract
The paper considers the designs of hinged mobile frontal barriers (HMFB, TMA) installed on cover vehicles (CP) and designed to improve safety on public roads during short-term road works. The comparison with trailed structures TMA made it possible to determine the advantages and disadvantages of various hinged structures. A review of the regulations for full-scale tests of the passive safety of the structures under consideration in the Russian Federation and abroad was carried out. A method is proposed for a two-stage digital virtual analysis of the TMA design at the design stage, which makes it possible to identify the features of work and evaluate the performance characteristics of the structure. The method is based on sequential finite element static and dynamic modeling of structure loading using numerical analysis. Some results of the design analysis of the typical design of the TMA are given.
