SU1785474A3 - Method for making elastic damping element from wire material - Google Patents

Description

The invention relates to mechanical engineering and aircraft construction and can be used for the manufacture of highly damped * honeycomb panels

Known methods of manufacturing ready-made tents by soldering or gluing deformed in the form of honeycomb strips of steel, aluminum, paper and other * materials, or straight * strips, followed by and *, deformation to form honeycombs

The disadvantage of the known * methods of making honeycomb * elements from steel, aluminum paper * strips is * low damping properties. The use of soldering or flattening in the manufacture of soyapg. And elements from strips made by pressing blanks from wire and "welding" removes and * degrades the properties, since solders and adhesives decay the mobility of wire elements

A known method of manufacturing elastic * elements of wire material, which consists in the formation of a rectangular mat from pieces of wire wound * in a spiral with a pitch equal to the diameter of the spiral and laid with mutual crossing of the axes, rolling the resulting mat into the workpiece and pressing it in a mold in the shape details

The disadvantage of the known method for the manufacture of elastic damping elements is that it provides the possibility of obtaining elements only of a simple geometric shape in the form of a cylinder, cube, cone, strip and does not provide the possibility of manufacturing an element in the form of honeycombs with a characteristic for none * spatial branched shape, represented by a contour of thin and * closed * walls and formed * cavities. The manufacture of honeycombs from strips by soldering or gluing impairs, as noted above, the damping properties

The aim of the invention is to reduce the level of vibration loads by obtaining a honeycomb element made of wire material with high damping properties

This is achieved by the fact that in the implementation of the method, including the operations of making a rectangular mat with a thickness equal to the height of the honeycomb, made of sections of weeding and wound in spirals with a pitch equal to the diameter of the spiral and stacked "with mutual crossing of the axes, if possible, uniformly and chaotically into the body The mat is installed evenly in a shallow manner, metal embedded elements in the form of hexagonal prisms, or plates with a height equal to the height of the honeycomb. The mat with embedded elements is placed in a rectangular mold, pressed to a density of 2-5 g / cm ³ and, after pressing, the embedded elements are removed. a single (monolithic) detail of a complex spatial shape, possessing high decimals (e and r u 10 U 1.1 M I S V O I ί STR a G 1I

Figure I shows a mat with embedded elements in the form of hexagonal prisms; in Fig. 2 - a pressed honeycomb control / damping element, in Fig. 3 - a mat with well-formed elements in the form of plates, in Fig. 4 - a pressed element from a mat with embedded elements in vice plates before stretching it to form a honeycomb

L hi The production of an elastic damping aperture from a wire material is carried out as follows

Prosopel at EN 708A with a diameter of 0.09 mm is wound into a spiral with an outer diameter of I ± 0.1 mm and weighed with an accuracy of 1.% The weighed spiral is stretched to a step of 0 4-4.1 m and placed □. in the form of a mat with mutual crossing of the axes of the spirals Opposite ι of the magician's paradise are bent parallel to each other to. raglerope concomitant; the inner cavity of the mold and compacted to a thickness equal to the height of the honeycomb.

Spreading the spirals in May 1 (Fig. 1], the insertion elements were evenly staggered in a checkerboard pattern, hexagonal prismatic elements 2 η. with m ⁴ n n l a. e m p e sgovaniya fitting pieces 2 is removed from the compact obtained claim vysokodempfirovanny cell element shown in FIG 2.

When using plates as embedded elements, manufacturing is carried out as follows. Wire Х18Н10Т with a diameter of 0.12 mm is drunk into a 5 spiral g with an outer diameter of 1 2 ± 0 1 mm and weighed with an accuracy of 1% Stretch the suspended spiral to a pitch of 2.1 + 1.3 mm and put it in the form of a mat with mutual crossing of the spiral axes ... The false edges of the mat are bent parallel to each other / to sizes corresponding to the inner cavity of the mold and compacted to a thickness equal to the height of the honeycomb. Pushing the spirals into the mat 1 (Fig. 3), 15 evenly staggered inserts 2 are installed in the form of rectangulars. " plates The mat made in this way is placed in a pre-form and pressed to a density of 5 g / cm ¹ After pressing, the embedded elements 2 are removed from the pressing and an element of wire material is obtained, shown in ¢ 11.1, 4 Stretching it to form a hexagonal * 'honeycomb , get the honeycomb highly damped element

The obtained honeycomb element has a continuous spatial structure consisting of thin "walls" and formed by them "hexagonal cavities" Since the walls are made of wire material, the honeycomb element has γητ 'ίηι deiffing characteristics? material
