Abstract (en)

The claimed damping device belongs to a group of safety devices that help to decelerate and stop a vehicle The damping device containing a front deflector representing a movable support installed on a guide with possibility of movement, sections of mass dampers and sectional side beams designed to provide the telescopic insertion of the front section of the side beam into the next one behind it. Each pair of sections of right and left side beams is limited by a horizontally oriented rectangular frame on a vertical base entering into a guide and fixed between relevant sections of right and left side beams. Ultimate rectangular frame of the damping device serves as a rear block, which is equipped with a rear fastening device rigidly connected to the guide. Damping device may contain mass dampers of the first and the second types. Each section of the mass damper of the first type is formed by twin vertical non-contacting sheet elements with zigzag shaped bends oriented towards each other, whereas each end of each element with zigzag shaped bend is bent outwards forming a through channel parallel to the centre line of the damping device. Each section of the mass damper of the second type represents a perforated end-to-end duct oriented horizontally relative to a through opening and perforation is made on each of four duct walls and at bends, with perforation at bends coming to both adjacent sides of the duct. Each section is limited by vertical plates, while several vertical plates rest on a lower bar of each rectangular frame. Front and rear vertical plates are fixed at front deflector and rear fastening, respectively. Sections of mass dampers of two types may be located in series. Sections of mass dampers of two types may be located alternately.
