Description
Technical field
The invention belongs to two technical fields of machinery and vibration, relate to a kind of compound vibration isolation and damping device, this device combines the advantage of steel-wire isolator and rubber vibration isolator, and it is limited to be applied to installing space, and the more abominable electronic equipment of vibratory impulse environment.
Technical background
Traditional isolation mounting generally adopts on engineering.If general vibration isolator vibration isolating effect is good, impact resistance is just poor so, and during the load that perhaps withstands shocks, the sphere of activities is very big, and during large impact, vibration isolator is two end faces or will be produced collision by device for vibration insutation and other equipment up and down.If the rigidity of vibrating isolation system is too big, do not reach vibration isolating effect; If rigidity is too little, the vibration isolating effect of this moment is good, and cushioning effect is poor again, the intrinsic contradictions between inevitable vibration isolation and the buffering.
Summary of the invention
The technical problem that the present invention will solve is: to the indeterminable contradiction between traditional existing vibration isolation of isolation mounting and the buffering; Design a kind of compound vibration isolation and damping device; Make electronic equipment satisfy under vibration and the shock response prerequisite good buffer effect.
The technological scheme that technical problem adopted that the present invention will solve is: steel-wire isolator and rubber vibration isolator are constituted compound vibration isolation and damping device; Compound vibration isolation and damping device have lower bottom base and last underframe; Lower bottom base is used for loading electronic equipment; Last underframe be trapped among on the bottom surface limit and above the ㄩ shape frame of lower bottom base bottom surface; Underframe on the bottom surface is being arranged on three limits of the seat surface of going to the bottom, and said steel-wire isolator symmetry horizontal arrangement realizes the single order vibration isolation function of three directions of XYZ between lower bottom base and last underframe and by screw; Said rubber vibration isolator vertically is installed between lower bottom base and the last underframe and by screw, when device resonance takes place and impacts, is carried out second order vibration isolation, buffering and the limit function of this moment by rubber vibration isolator.Compound vibration isolation of the present invention and damping device possess the non-linear rigidity isolation characteristics, and when second order vibration isolation forced vibration stable state, the natural frequency of device only slightly changes in the natural frequency scope of single order steel-wire isolator, thereby reaches rapid reduction resonance peak.
Rubber vibration isolator of the present invention is by double-screw bolt, first axial bushings, second axial bushings, radially lining; Spacing bush ring, axial limiting piece and nut are formed, and on lower bottom base, spacing bush ring passes through screw on last underframe to double-screw bolt through screw; Nut plays locking fastening effect, and first axial bushings and double-screw bolt are bonding, and second axial bushings and axial limiting piece are bonding; Radially lining is bonded on the spacing lining evil idea; Two-stage vibration isolation and buffering are divided radial and axial, radially rely on to go up underframe, radially spacing lining and double-screw bolt completion, realize vibration isolation, the buffering and spacing of horizontal X axle and Y direction; Axial limiting relies on axial bushings, nut, goes up underframe and double-screw bolt completion, realizes vibration isolation, the buffering and spacing of vertical Z-direction.
The main design parameters of this compound vibration isolation buffering device comprises: during the single order vibration isolation, and the nominal load of three directions of steel-wire isolator, mean rigidity and energy energy storage value (can hold); Axially and radially carry out the transition to the maximum free displacement of permission between the transition zone of second order vibration isolation from the single order vibration isolation, and the mean rigidity of second order rubber vibration isolation, damping (perhaps can hold) etc.
Working principle of the present invention is: in the scope of broadband territory; Steel-wire isolator is as the vibration isolation main body; Have lower natural frequency,, have extraordinary vibration isolation effect in all the other wider frequency except that lower natural frequency annex has 2 times of left and right sides resonance peaks; Its vibration transmissibility is about 20%, and vibration isolating effect is fine; And by device for vibration insutation resonance the time when impacting, utilize rubber vibration isolator to carry out second order vibration isolation and buffering again, this moment, the rigidity of vibrating isolation system was both sums, the damping of system increases again, thereby reaches the effect that reduces resonance peak and buffering.
The beneficial effect that the present invention and existing technology contrast are had is:
This device uses " traditional steel-wire isolator and rubber vibration isolator " combination, constitute a kind of compound vibration isolation buffering device, and this device all can carry out effective vibration isolation and buffering in three directions (X, Z, Y).It is wide that this device possesses steel-wire isolator vibration isolation frequency domain; The vibration isolation efficiency advantages of higher; Owing to adopt rubber vibration isolator second order vibration isolation and buffering, reduced the resonance peak of single order steel-wire isolator, and played the effect of buffering; Avoid to be produced secondary collision, solved the contradiction of intrinsic vibration isolation of traditional vibration isolator and buffering to a certain extent by device for vibration insutation and other equipment.When second order forced vibration stable state; The natural frequency of this device slightly changes near the natural frequency of single order steel-wire isolator; Thereby reach rapid reduction resonance peak; Electronic equipment is being satisfied under vibration and the shock response prerequisite, and it is best that cushioning effect reaches, and avoids will being produced secondary collision by device for vibration insutation and other equipment.Overcome the shortcoming of traditional isolation mounting.
This device structurally splits traditional rubber shock absorber, merges with the electronic equipment of need vibration damping, greatly reduces the whole boundary dimension of vibration damping equipment and electronic equipment, particularly is suitable for the limited situation of installing space.
Adopt the electronic equipment behind this compound vibration isolation buffering device to rise appreciably working life, electronic equipment anti-vibration and impact property improve, and the reliability of equipment operation significantly improves.Reach the optimization of anti-vibration and shock design.
