Abstract
The invention provides a steel-wire-rope compounded rubber type vibration isolator. A steel wire rope of the steel-wire-rope vibration isolator is embedded in a rubber layer. The thickness of the rubber layer and the diameter of the steel wire rope are arranged by a certain proportion, namely A is equal to 2-2.4d, wherein d is the diameter of the steel wire rope, and A is the thickness of rubber that wraps the steel wire rope. Especially, as the internal-layer rubber on the upper load surface and the lower load surface of a metal ring is thickened, the hollow chamber of the round section of the steel-wire-rope vibration isolator is dumbbell-shaped. Furthermore, h is equal to 2H/5, wherein the H is the distance between the center of the upper load surface and the center of the lower load surface of the metal ring; and h is the distance between the thickened positions of the upper internal layer rubber and the lower internal layer rubber when no load exists. The steel-wire-rope compounded rubber type vibration isolator has two vibration isolation effects and a good damping characteristic, the damping function of three DOF (degree of freedom) can be realized effectively, and the fatigue crack problem of the steel wire rope due to continuous impact can be avoided simultaneously, therefore the steel-wire-rope compounded rubber vibration isolator is applicable to the vibration isolation of a severe vehicle cross-country motion state.
Description
Technical field
The present invention relates to a kind of Vibration Absorbing System Design of electronic equipment, especially a kind of steel-wire-rope compounded rubber type vibration isolator.
Background technique
In electronic technology growing today, the vibration isolation of electronic equipment requires more and more higher, especially
The Ku frequency rangeIn satellite communication system
" communication in moving "Vehicle-mounted
Communication antenna, the vibration isolation of electronic equipment has been proposed harsher requirement.
The vibration isolator that adopts of satellite communication system only required that guaranteeing that mobile unit equipment in harsh cross-country process does not damage got final product in the past, and did not require that assurance equipment works under cross-country status.Along with the development of control technique,
The Ku frequency rangeSatellite communication has really realized
" communication in moving ", require system's vibration isolator can work under cross-country status by assurance equipment.
The vibration isolator that is widely used now mainly contains rubber vibration isolator, metal spring vibration isolator, air cushion shock absorber, without resonance peak damped type vibration isolator, steel-wire isolator etc., all there is such or such defective in they, are difficult to satisfy the vibration isolation requirement of the antenna equipment in system.
Under the cross-country movement state of vehicle, harsh vibration condition and strong impact strength, a kind of new vibration isolator need to be arranged, it can have significant vibration isolating effect, has again good damping characteristic, and can effectively realize " Three Degree Of Freedom " cushioning effect, avoid simultaneously the FATIGUE FRACTURE PROBLEMS due to wire rope that bump causes.
Existing steel-wire isolator (being the vibration isolator of the spring structure of helically coiling) be also the metal spring vibration isolator a kind of, be that a kind of load directly is pressed in the vibration isolator on the spiral metal spring shackle, therefore the load surface up and down of metal ring is equipped with a load board, spring perforation or fix in the load board relevant position in the load board.The spring of this " Three Degree Of Freedom " damping that is a kind of, but under the cross-country movement state of vehicle, bad, the wire rope of damping is metal elastic circlip fatiguability.
Summary of the invention
The objective of the invention is: propose a kind of vibration isolator with rubber type vibration isolator and steel-wire isolator organic composite, i.e. steel-wire-rope compounded rubber type vibration isolator.This kind steel-wire-rope compounded rubber type vibration isolator had both had both vibration isolating effects, and good damping characteristic is arranged again, can effectively realize " Three Degree Of Freedom " cushioning effect, avoided simultaneously the FATIGUE FRACTURE PROBLEMS due to wire rope that bump causes.The vibration isolation that is applicable to the cross-country movement state of harsh vehicle is used,
Technological scheme of the present invention is: steel-wire-rope compounded rubber type vibration isolator, the steel wire of steel-wire isolator is embedded in rubber layer, and the thickness of rubber layer and the diameter of wire rope arrange by a certain percentage, i.e. A=2-2.4d, d is the diameter of wire rope, and A is the rubber thickness of wrapped wire rope; Can adopt natural rubber etc.
Improvement of the present invention is: the internal layer rubber thickening of the load surface up and down of metal ring; thereby the hollow cavity place of the circular section of steel-wire isolator becomes a special shape; it is dumbbell-like shape; when guaranteeing vibration isolator the up and down load surface be fully closed when bearing maximum exercise load; the internal layer rubber surface contact of up and down load surface; wire rope is can excessive deformation not tired, the unlikely fracture of protection wire rope.
The invention has the beneficial effects as follows: propose a kind of vibration isolator with rubber type vibration isolator and steel-wire isolator organic composite, this kind steel-wire-rope compounded rubber type vibration isolator had both had both vibration isolating effects, good damping characteristic is arranged again, can effectively realize " Three Degree Of Freedom " cushioning effect, avoid simultaneously the FATIGUE FRACTURE PROBLEMS due to wire rope that bump causes.The vibration isolation that is applicable to the cross-country movement state of harsh vehicle is used, and still has significant vibration isolating effect under harsh vibration condition and strong impact strength.
Description of drawings
Fig. 1 is the steel-wire-rope compounded rubber type vibration isolator schematic cross-section.
Embodiment
The present invention embeds the steel wire 1 of steel-wire isolator in natural rubber 2, and the thickness of rubber layer and the diameter of wire rope arrange by a certain percentage, i.e. A=2.2d, and d is the diameter of wire rope, A is the rubber thickness of wrapped wire rope; Improvement of the present invention is: the internal layer rubber thickening of the load surface up and down of metal ring, thereby the circular section of steel-wire isolator becomes a special shape, it is dumbbell-like shape, when guaranteeing vibration isolator the up and down load surface be fully closed when bearing maximum exercise load, the internal layer rubber surface contact of up and down load surface, steel wire
Size relationship is exactly several feature of the present invention:
1, A=2.2d here d be the diameter of wire rope, A is the rubber thickness of wrapped wire rope;
2、l=L/4；
3、h=2H/5。
Distance H between the load surface up and down center of metal ring, the distance L between the metal ring center, left and right of metal ring, l is the width of internal layer rubber thickening place, the distance when h is non-loaded between thickening place of up and down internal layer rubber.
The circular section of steel-wire isolator becomes the space of dumbbell-like shape, when guaranteeing vibration isolator the up and down load surface be fully closed when bearing maximum exercise load, and the internal layer rubber surface contact of up and down load surface, steel wire can produce damping elastomer in limited distortion.Step when making is as follows: choose suitable steel-wire isolator, determine steel wire diameter, pitch of the laps size and installation form; According to the size of steel-wire isolator, in the described ratio of above-mentioned schematic cross-section, design rubber layer size; Select natural rubber, by mold injection molding, with the steel wire parcel of steel-wire isolator.
