Description
Technical field
The invention belongs to antivibration areas, relate generally to a kind of irrotational displacement isolator platform, specially a kind of single connecting rod
The linear adjustable rigidity irrotational displacement isolator platform of cross slider type, the electro-optical system especially suitable for diagonal displacement sensitivity.
Background technique
Civilian electro-optical system plays important in environmental monitoring and protection, searching rescue, anti-smuggling drug law enforcement and anti-terrorism field
Effect, is equipped on different transport agents, compared to static use environment, can promote at double effective utilization: " that stands is higher ",
" that sees is farther " and " identification clearer ", the accuracy and clarity for acquiring the video image of output are that operator makes
The important evidence of judgement and decision.
External disturbance is always to influence the key of electro-optical system image quality, the vibration of especially common transport agent itself
It the dynamic, gas shock that is encountered in carrier movement and itself jolts, it all can be to the stabilization of system imaging picture as major disturbances source
Property and clarity formed interference.Current electro-optical system combines inhibition frequently with the mode of active vibration isolation and passive type damper combination
External disturbance.It is limited to servo bandwidth, the common sphere of action of active vibration isolation is only low-frequency excitation section, and the disturbance of high band decays
The completion of passive type damper is then relied primarily on, the latter is also main study subject of the invention, and the mechanism of action is similar to low pass filtered
Wave device can effectively inhibit 1.4 times of its intrinsic frequency or more of forcing frequency, thus when selecting damper, ideal shape
State is that its intrinsic frequency is lower, and Disturbance Rejection range is broader.
To make full use of limited space, obtaining more good effectiveness in vibration suppression, damper often uses in groups, and according to
The difference of damper group layout, generally can be divided into built-in damper group and external damper group, the former is placed in inside electro-optical system,
It is distributed around optical sensor, by accurately arranging, it can be achieved that the elastic center of damper group is overlapped with optical sensor mass center,
To can inhibit rotary motion of the optical sensor around damper, and according to optical imaging concept, optical sensor with it is to be measured
Linear relative motion between target is smaller on imaging effect influence, therefore the damper group of the type can give full play of damper
Desired effect.
But works as electro-optical system and be limited to inner space volume and installation site, lead to that damper group system can only be placed in
When external, the mass center of optical sensor can not be overlapped with the elastic center of damper group, and electro-optical system easily occurs to surround at this time
The rotary motion of damper line, and the intrinsic frequency selection of damper is lower, shows rotary motion and is more obvious, it is similar
" pendulum " phenomenon common in life, according to optical imaging concept, the change of the relative angle between optical sensor and object to be measured
Changing influences imaging effect obviously, it is random in imaging picture that target intuitively to can be observed, it will be apparent that migration everywhere, damper
Intrinsic frequency is lower, should obtain preferably disturbance attenuating, but after coupling above-mentioned " pendulum " effect, is obtained from anti-
Worse image frame can all bring very big puzzlement to operator's accurate observation, judgement and selection target.To solve this problem,
Common methods are to sacrifice the high-frequency suppressing ability of damper group, switch to select biggish damper group reduction " pendulum " effect of rigidity
Angular displacement frequency and amplitude.
And as electro-optical system application environment becomes increasingly complex, imaging definition requirement is higher and higher, and to photoelectricity
The layout type of the increasingly harsher design constraint of system bulk weight, external damper group certainly will become the hair being hard to avoid
Direction is opened up, therefore be badly in need of a kind of irrotational displacement isolator platform to take into account what electro-optical system was faced when using external damper
Additional " as moving " and " image rotation " phenomenon are eliminated or weakened to " pendulum " effect problem and high frequency components inhibitory effect, to improve
The integrated imaging effect of photoelectric sensor.
Through information inquiry it is found that Chinese patent CN103511549B discloses a kind of a kind of " irrotational displacement parallel connection vibration damping dress
Set ", which includes moving platform, fixed platform and the four completely identical in structure branches and the vibration damping bullet that connect two platforms
Spring can be limited the relative rotation between moving platform and fixed platform by four branches being symmetrically and evenly distributed, pass through edge
Disturbance decaying is realized in the use of multiple unidirectional shock-absorbing springs of three orthogonal directions arrangement, to reach the effect of irrotational displacement isolator
Fruit.
But in actual use, it has been found that above-mentioned apparatus has the following problems:
(1) it relies primarily on constraint that double link and single cylindrical pair realize diagonal displacement freedom of motion, subtracts due to second
Oversized relationship, causes the cylindrical shaft for the cylindrical pair connecting with moving platform too long shared by vibration spring, and two connecting rods are narrow, knot
Structure is thin, and thin structure type seriously constrains the comprehensive constraint ability of device, especially when electro-optical system load is larger,
Certain angular displacement campaign can still occur for the latter, and irrotational displacement restriction ability is poor, and often block because of deforming excessive
It is stagnant.
(2) occupied space is larger, leads to the axis mistake of cylindrical pair in addition to the layout of the second shock-absorbing spring occupies to take measurements greatly
It is big outer；Above-mentioned apparatus limit must use four branches being symmetrically and evenly distributed, therefore electro-optical system installation site by
To limitation, in the case where can not arranging four identical structures, which is not available.
(3) resetting difficulty is high, and for opposite installation two-by-two, the branch used in pairs must for the branch which uses
It must just be avoided that in linear movement and locking does not occur in the direction of motion remained exactly the same；Opposed branch mechanism must protect
The shaft for demonstrate,proving cylindrical pair is parallel enough, and the adjacent branch used must keep having enough accuracy just between the direction of motion
It hands over, is just unlikely to be formed in other side moves and hinder.
(4) maintainability is poor, which is used to eliminate branch's group of angular displacement and the spring for convergent response exists
It is cross-linked with each other, can not independently dismount in structure installation, and after any unit of dismounting, ideal work can be just restored to by being both needed to accurate adjustment
Make state, has in use not convenient more.
(5) effectiveness in vibration suppression is difficult to adjust, and above-mentioned apparatus realizes the linear of three directions using up to 12 independent springs
Decaying, easily because of the installation of spring, fixed position, individual performance difference and the factors such as coupled relation is bad during being applied in combination
Bring undesirable attenuating；The process of the spring rate according to needed for expected attenuating inverse is also abnormal cumbersome simultaneously, is
Using bringing very big inconvenience.
Therefore it is badly in need of that a kind of structure is simple, adjustment is convenient, bearing capacity is strong, motion credibility is high, use space adapts to energy
Power is strong, maintainability is good and Angleless displacement vibration convenient for upgrading.
