Buffering and energy absorption filling pipe

Abstract

The invention belongs to buffering and energy absorption components and discloses a buffering and energy absorption filling pipe. The problem that an existing foamed aluminum filling pipe is poor in energy absorption effect is solved. Aluminum-based composite foam materials are filler to be made into an aluminum-based composite foam filling pipe component, the energy absorption effect many times that of an ordinary foamed aluminum filling pipe component is achieved, the disadvantage that the aluminum-based composite foam materials cannot be independently used as an energy absorption or bearing structure due to poor intensity is overcome, and the high-intensity aluminum-based composite foam filling pipe component can fully play and integrate the advantages and mechanical property of various materials when bearing explosive blast, impact or other extreme loads, not only has the independent bearing capacity, but also has the outstanding advantages of being high in stability and energy absorption capacity and capable of working in the extreme environment and the like. Equivalent static compression tests are conducted on the buffering and energy absorption filling pipe and prove that the buffering and energy absorption filling pipe has the energy absorption capacity and mechanical property superior to those of the ordinary foamed aluminum filling pipe. Compared with a traditional hollow steel pipe and the ordinary foamed aluminum filling pipe, the crushing force and the energy absorption capacity are greatly improved.

Description

technical field [0001] The invention belongs to a buffer energy-absorbing component, in particular to a buffer energy-absorbing filling pipe. Background technique [0002] After the "911" World Trade Center terrorist attack in the United States, the anti-blast design, calculation and analysis methods and protection strategies of large public buildings have attracted worldwide attention, and the anti-blast and impact resistance of engineering structures has gradually become a research field in the field of civil engineering. hotspot. [0003] Thin-walled metal tubes commonly used in engineering are the most traditional and effective buffer energy-absorbing structures, and have been widely used in the collision energy dissipation systems of almost all vehicles such as automobiles, railway trains, aircraft and ships. Aluminum foam is a porous metal material. During the impact compression process, the stress in the plastic deformation stage on the stress-strain curve is almost ...
