IMPACT ENERGY ABSORBER Russian patent published in 2005 - IPC

FIELD: rail vehicles and different industries.

SUBSTANCE: proposed device contains energy absorbing part, movable and stationary support plates. Energy absorbing part can be made up of metal plate members, thickness from 2 to 10 mm, extreme ones being secured on support plates with flat section and camber section and forming cellular structure in section consisting of great number of hexahedrons in section by planes passing through vector of external resultant force with provision of impact energy absorbing owing to flexural strains in metal plate members mainly on chamber sections. Energy absorbing part can contain great number of cells, each formed by two flat metal plates, thickness from 2 to 10 mm, arranged square to external force vector, and two metal plates, thickness from 2 to 10 mm, placed in between, with initial camber in direction square to vector of external force and thrusting against middle of flat metal plates of adjacent cells. Extreme metal plates are secured to support plates with provision of absorption of impact energy owing to flexible strains of metal plates in places of maximum camber and flexural strains of flat metal plates in places of butt-joining of metal plates. Energy absorbing part can be made in form of cellular structure consisting of great number of rectangles made up of metal plate members, thickness from 2 to 10 mm, extreme ones being secured on support plates. Some metal plate members coincide with direction of external force and thrust against middle of metal plate members of adjacent cells arranged square to vector of external force with provision of impact energy absorbing owing to flexural strains in units of intersection of metal plate members. Device provides absorption of impact energy of the order of 0.5-2.5 MJ.

EFFECT: provision of effective absorption if impact energy at relatively uniform overloads to which passengers are subjected.
