The Application of Chopped Steel Wire Ropes into Curved and Twisted Fibers

Abstract

The invention discloses application of bending torsion filaments obtained by chopping a steel wire rope, and particularly relates to application of a mechanical structure part made from a metal porous material formed by pressing and sintering bending torsion filaments obtained by chopping a steel wire rope in directly achieving porous rigid vibration attenuation. According to different using conditions, the porosity of the metal porous material which is formed by pressing and sintering bending torsion filaments obtained by chopping the steel wire rope is adjustable, the porosity mainly ranges from 20% to 75%, and the loss factor ranges from 0.01 to 0.06. The sintered bending torsion filament metal porous material is machined into a part to be applied to a mechanical structure for rigid vibration attenuation, the porosity of the filament porous material ranges from 20% to 50%, and the loss factor ranges from 0.01 to 0.04. The metal porous material can be directly machined into the bearing structural part, and mechanical system porous light rigid vibration attenuation is achieved.

Description

technical field

[0001] The invention relates to the application of metal porous materials in the field of vibration reduction, in particular to the application of a steel wire rope chopped into bent and twisted fiber wires. Background technique

[0002] Metal fiber porous materials using metal fiber as raw materials have many advantages. Large-scale production of fiber filaments has a mature technology. Most metals, including tungsten and zirconium, can be made into filaments / fibers. Matrix materials with high strength and few defects can be easily obtained from filaments, such as stainless steel. Wire, carbon steel wire, aluminum alloy wire, copper fiber, iron chromium aluminum fiber and titanium fiber. The easy-to-obtain metal wire not only reduces the production cost of the metal fiber wire porous material, but also can be easily controlled to form various shapes required for the preparation of the metal fiber wire porous material. From the aspects of manufacture, perfo...
