Abstract

This invention relates to mechanical engineering, in particular to shock absorbers. The purpose of the invention is to increase the efficiency of vibro-shock isolation by increasing friction losses, provided both by the choice of material with high internal friction and by friction between structural elements. The vibration impactor contains elastic rods 4, for example, of cables, which enclose the package body of toroid-shaped shells of 5 C-shaped sections of resilient damping material, the internal thickness of which is filled with bodies of 6 of similar material, and additional elastic rods 7. Due to internal friction provides a characteristic with a wide hysteresis loop. Used tires of vehicles and cuttings from them can be used as shells 5 and bodies filling them 6. 1 hp ff, 6 ill. and 9 (L Fi2.

The invention relates to the field of mechanical engineering, in particular, to vibroelectric engineering, and can be used for damping structural elements in heavy loaded machines and mechanisms.

The purpose of the invention is to increase the efficiency of vibration impact by increasing friction losses.

shell filling; 6 shows an embodiment of toroidal shells from sectorial parts.

The vibration impactor consists of a cylindrical body 1 with a base 2 and a piston 3, inside which resilient rods 4 are located, contacting or fixed in the base 2 and the piston 3 and made, for example, from cables, to hunt the body of a package of toroidal shells of 5 C-shaped cross section of elastic-damping material located between the piston 3 and the base 2. The inner cavity of the shells 5 or part of it is filled with bodies 6 of elastic-damping or similar material. In addition, the vibration impactor can be equipped with additional elastic rods 7 located circumferentially on the side of the outer surface of the body i and contacting or fixed in the base 2 and the piston 3. The elastic rods 7 can surround the shells 5 or pass through the holes in them. As shells 5 and bodies filling them 6 can be applied

used vehicle tires and clippings.

The vibration impactor works as follows.

When an external load is applied to the piston 3, the latter compresses the elastic rods 4, the toroidal shells 5 and the bodies filling them 6, as well as the elastic rods 7. When the load is reduced or terminated, the piston under the action of the elastic rods 4, the shells 5 and body 6 returns to its original position. At the same time, due to the internal friction, the characteristic of the vibro-impactor has a wide hysteresis.
