Problems solved by technology

Although the metal fiber porous material can have high strength and realize the integration of structure and function, it is rarely used as a load-bearing structure at present. It is still made into a sandwich structure as a core like a porous medium such as honeycomb and foam to realize Lightweight vibration reduction, impact resistance and energy absorption applications, while the combination between the core and the upper and lower panels increases the process cost

Embodiment 1

[0054] The twisted and twisted fiber wire porous pad is inserted between the gear reducer transmission system and the base and fixed to achieve vibration reduction of the entire system.

[0055] Implementation results

[0056] 1) Comparison of the vibration velocity spectrum between the response point B1 plus the porous pad system and the original system is as follows: Figure 9 , Figure 10 with Figure 11 shown. Figure 9 The resonant vibration frequency is reduced from 10 to 4 after adding porous pads radially. In the original system, the maximum peak amplitude of 8.25mm / s corresponding to 99.38Hz decays to 0.83mm / s, and the vibration frequencies after this vibration frequency all disappear after adding porous spacers. The maximum peak value is generated at 89.38Hz, and its amplitude is 2.84mm / s, which is only 0.95mm / s higher than the amplitude of 1.89mm / s in the original system, but far smaller than the maximum amplitude of the original system's resonance peak. Figur...

Embodiment 2

[0069] Example 2 The porous ring of bent and twisted fiber filaments is assembled between the input shaft of the gearbox and the inner ring of the intermediate shaft bearing and the journal, and is tightly fitted and fixed, such as Figure 12 As shown, the vibration reduction of the whole system is realized.

[0070] Implementation results

[0071] 1) The vibration velocity spectrum comparison between the response point B1 plus the porous ring system and the original system is as follows Figure 13 , Figure 14 with Figure 15 shown.

[0072] Such as Figure 13 The radial original system shown has a maximum peak of 8.252mm / s at 99.37Hz. After the porous ring is added, the resonance here disappears, and a new maximum peak of 3.04mm / s occurs at 88.13Hz, which is about 37% of the original system. Figure 14 All the vibration frequencies after 174.36Hz of the original axial system shown in the figure almost disappear after the porous ring is added, and the amplitudes of very ...

Embodiment 3

[0087] The difference between this embodiment and Embodiment 2 is that the porous ring of twisted fiber filaments is assembled between the input shaft, the intermediate shaft, the inner ring of the output shaft bearing and the journal.

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...
