Embodiment Construction

[0028] The technical solutions in the various embodiments of the present invention will now be described in detail with reference to the drawings in the embodiments of the present invention.

[0029] Such as Figure 4 The substrate 1 shown is a steel beam with a length of 1200mm, a width of 100mm, and a thickness of 2mm; the flexible string 5 adopts a latex tube with an outer diameter of 2mm; mm through holes; the cover plate 2 is made of steel, with a length and width of 130mm, a thickness of 2mm, and rounded corners of 5mm.

[0030] Frame 3 is made of nylon plastic and made by additive technology. The profile height is 30mm, the length and width are 130mm, the inner wall thickness is 5mm, and the four corners are rounded with 5mm similar to the cover plate. In the middle area of ​​the upper and lower positions, the plate thickness is 2mm and the height is 10mm. There are 8 limit card slots evenly distributed on each rib. The card slots are excellent arcs with a diameter of ...

Abstract

The invention discloses a conveniently-mounted small-size adjustable flexible array dynamic vibration absorption structure. The structure comprises a frame, cover plates and at least one vibration unit array, wherein the vibration unit array comprises a flexible string and a plurality of perforation quality units penetrating through the flexible string. Each vibration unit is composed of a perforation quality unit and a section of flexible string. The perforation quality units penetrate through the flexible strings as required, the vibration unit arrays are mounted on frame limiting clamping grooves as required, two ends of the flexible strings are fixed to the two sides of the frame, the cover plates are mounted at the upper end and the lower end of the frame, and then the assembling of the structure is completed. When the structure is used, the different dynamic vibration absorption structures with the material parameters designed are bonded to a controlled base body. The technical scheme has the advantages that the system is simple, reliable, low in cost and convenient to disassemble, modify and manufacture in batches; and the vibration energy of a specific frequency can be absorbed, the vibration energy under multiple frequencies can also be absorbed, and an obvious effect on low-frequency vibration noise suppression is achieved.

Description

technical field [0001] The invention relates to the field of vibration and noise control, in particular to a conveniently installed and small-volume adjustable flexible array dynamic vibration-absorbing structure. Background technique [0002] Mechanical vibration and noise control has always been a very important research topic in the engineering field. [0003] Classical vibration and noise control technologies can generally be divided into dynamic vibration absorption, vibration isolation, damping vibration reduction, and active vibration control. Among them, the development of dynamic vibration absorption technology has been divided into active control and passive control. Mature, simple system, low cost, relatively reliable and stable, but with the development and update of technology, the traditional passive control technology is no longer suitable for today's requirements for lower noise levels in wider frequency bands, according to traditional passive control methods...
