Definitions

  • the invention relates to an apparatus for absorbing energy with at least two spaced-apart plates, wherein the first plate is arranged such that the force associated with the energy to be absorbed first acts on this plate.
  • the device can also be created by a tubular form.
  • the invention further relates to a use of the device as a mine-protection device as well as to a use of the device as a crash cushion for a motor vehicle.
  • Lightly armored vehicles often have no or only insufficient protection against pressure waves triggered by mines near the ground, because the use of a correspondingly strong bottom-side armor for weight reasons is not possible. This applies in particular to air-armored armored vehicles, which must not exceed a certain maximum weight.
  • a mine-protection device for armored vehicles which consists essentially of two spaced apart by web-shaped spacers plates.
  • the first plate faces the ground, so that the pressure wave at a mine detonation first acts on this plate, which transmits the forces exerted on it by the pressure wave of the detonation forces on the spacer parts.
  • the spacers are designed to absorb energy relative to the second plate compressible.
  • the spacers are designed in terms of their arrangement, dimensioning and material properties such that a deep-pass damping of the pressure wave takes place.
  • the first plate of the known mine-protection device consists of light metal, it is in the rigidly trained second plate to armor steel, which in turn leads to an increase in weight of the corresponding vehicle.
  • composite panels are for example from the DE 10 2005 013 660 A1 , of the DE 10 2005 050 981 A1 as well as the DE 10 2007 022 143 A1 known.
  • the invention has for its object to provide a device of the type mentioned above, which has a relatively low weight and yet causes a simple way a high energy absorption.
  • preferred uses of this device are disclosed in particular in motor vehicles.
  • the invention is based essentially on the idea, using a viscosity, flow or flow brake o. ⁇ ., Which serves by the flow resistance of the medium / material (filler) at a defined cross section for energy absorption or energy absorption or energy conversion, the potential hazard the event - pressure wave by mine action - to minimize.
  • an arrangement consisting of at least two spaced-apart plates is filled with a filling material which, upon compression of the two plates, can escape through at least one outflow opening with a defined flow cross-section. Due to the flow resistance of the filling material in the region of the defined flow cross section, the desired energy absorption then takes place.
  • a filling material which, upon compression of the two plates, can escape through at least one outflow opening with a defined flow cross-section. Due to the flow resistance of the filling material in the region of the defined flow cross section, the desired energy absorption then takes place.
  • Both liquids are suitable as filling material correspondingly high viscosity as well as gels, plastic or metal foams and granules. But other suitable materials come as a filler in question, which should be as light as possible to minimize weight of the device according to the invention.
  • the first plate and its associated spacers are designed in terms of their material properties, wall thickness and construction such that they with appropriate force on the first plate are deformable at least in partial areas relative to the second plate.
  • the second plate is rigid. What can be achieved for example by two sandwiched sheets of light metal or steel, which are connected to each other via rigid support members.
  • the two plates are connected to one another via side walls, wherein an outflow opening is located in one or both side walls.
  • the spacers may be web-shaped so that the filler material can easily flow around these spacers.
  • the spacers may also be formed rib-shaped, so that chamber-shaped portions are formed between the two plates. Due to the light support ribs, the respective medium can either flow through almost unhindered. But there is also the possibility that at least a part of the rib-shaped spacers is provided with flow openings. In total, thus several absorption segments are formed.
  • the support ribs can be designed so that they deform in the event of an incident and do not lead to a deformation of the vehicle interior floor.
  • the shape of the vehicle floor can be arbitrary, for example, flat, curved, angled etc.
  • the first plate and the spacer parts can preferably be made of a light metal, for example an aluminum alloy.
  • a tubular part or a pipe can also form the device, wherein spacer parts, outflow opening etc. are integrated, which in turn fulfill the same tasks / functions as in the case of a plate arrangement.
  • the device according to the invention can preferably be used as a mine protection device, which can be arranged in the floor area of a vehicle, the first plate of the device being arranged on the ground floor side and the second plate arranged on the vehicle being designed as a rigid inner floor of the vehicle.
  • the device according to the invention can be arranged both on the front side and the rear side on the corresponding motor vehicle.
  • the device according to the invention it is also conceivable to integrate the device according to the invention, for example, in the side walls of the motor vehicle.
  • the benefits include reducing the risk of injury to the vehicle crew and lighter weight compared to steel or composite panels. Due to the cross-sectional adjustment can be adjusted between a hard or soft coupling of the pressure wave and thus the absorption. That is, the degree of reduction is determined not only by the viscosity of the material but also by the cross section to be flowed through in the event of an event.
  • the figure shows the cross section of a mine-protection device according to the invention shown greatly simplified again.
  • the mine protection device is indicated by the reference numeral 1.
  • the mine protection device 1 is formed by a type of viscosity, flow or flow brake, which can receive a filling material 13 and has at least one outlet opening 10 (11). Due to the viscosity of the material used, the adjustable in a particular embodiment cross section and thus the actual flow and flow properties, the degree of reduction is adjusted or regulated.
  • the device 1 or brake is composed in a simple embodiment substantially of two spaced-apart surfaces 2, 3, here two plates together, which are preferably connected to one another via raised side walls 4, 5 and / or a plurality of web-shaped spacers 6 and for receiving the Medium or filling material 13 serve.
  • the raised side walls 4, 5 have the advantage that the medium 13 can be used again high pressed and is not lost. Side collecting containers can also take over this task.
  • the first plate 2 and the web-shaped spacers 6 are designed in terms of their material properties, their wall thickness and their construction such that they are deformable with a corresponding force on the first plate 2 at least in partial areas relative to the second plate 3, the second plate 3 as rigid inner bottom of the vehicle formed.
  • the second plate 3 for example, consists of two sandwiched plates 7, 8, for example, a light metal, which are connected to each other via rigid support members 9.
  • each of the two side walls 4, 5 there is an (optionally) closable outflow opening 10, 11 with a predefined flow cross section.
  • the interior space 12 located between the two plates 2, 3 is filled by a filling material 13, for example a plastic foam.
  • the resulting pressure wave first acts on the deformable first plate 2 and presses it in the direction of the rigid second plate 3.
  • the web-shaped spacer parts 6 are compressed or bent out.
  • the filling material 13 located in the interior space 12 between the plates 2, 3 is pressed at least partially through the outflow openings 10, 11, so that the desired energy absorption occurs due to the flow resistance of the filling material 13 in the region of the outflow openings 10, 11.
  • the means or surfaces 2, 3 can be formed in particular for smaller dimensions for crashes but also by a kind of tube / bumper, etc. (not shown in detail), which may be U-shaped bent and fastened to a vehicle.
  • the top of the tube should take over the task of the rigid plate 3, which of course an additional, rigid plate can support the tube.
