Problems solved by technology

[0003] At present, the common porous metal sandwich panels are mostly single structures such as corrugated or foamed aluminum, which only have a single function, or a single function is strong while other functions are weakened, such as the transverse shear strength and bearing capacity of metal corrugated sandwich panels. Strong, but the energy dissipation performance is poor, and the metal rubber material has a large damping coefficient in the wide frequency range, the loss factor is 0.1 to 0.3, and its energy absorption and vibration reduction effect is significant

Embodiment 1

[0023] 1) First, the flattened aluminum alloy plate is molded and folded to form a corrugated structure core 2, and then the formed corrugated structure core 2 and the panel 1 of the aluminum alloy plate are cleaned to remove oil and rust. The corrugated structure core 2 and the panel 1 are glued together by casting glue to form a corrugated structure lattice metal sandwich panel, see figure 1 ;

[0024] 2) Then, according to the space size of the hole 4 in the core body 2 of the corrugated structure, the metal rubber blank whose metal wire material is OCr18Ni9Ti is put into a corresponding mold and pressed repeatedly by a press to make it match the hole 4 in the core body 2 of the corrugated structure. Triangular prisms or trapezoidal prisms that are suitable for the space size of the prisms. During the pressing process, vibration loads are applied in the direction perpendicular to the pressing forming to obtain members with three-dimensional damping and uniform strength. Mi...

Description

technical field [0001] The invention relates to the technical field of load-bearing vibration-damping and energy-absorbing structural materials, in particular to a metal corrugated-metal rubber composite material and a preparation method thereof. Background technique [0002] Metal rubber can withstand large deformation. When deformed under load, the metal wires squeeze and slide each other to generate friction, which can dissipate a large amount of energy, thereby playing the role of vibration reduction. Metal rubber has many advantages such as good damping performance, strong environmental adaptability, can be used in complex load conditions, long service life, structure and performance can be designed, not only can meet the needs of harsh environments such as aerospace, military equipment, petrochemical offshore platforms, etc. , can also be used in machinery, transportation, civil engineering and other fields. Metallic rubber is a kind of elastic porous material. In add...
