Description
Technical field
The invention belongs to aircaft configuration activity rudder face strength test protection techniques, and in particular to one kind is lived for aircaft configuration
The photoelectric protector of dynamic rudder face strength test.
Background technology
Usual aircraft rudder surface static and fatigue test is static loading, regardless of following loading problem, protection dress
Putting can be realized using limit switch.And in aircaft configuration activity rudder face following loading, loading device is with aircraft rudder surface
It rotates and moves.It is realized and protected with limit switch, just seemed helpless.In order to prevent due to fortuitous event during experiment
Cause movable rudder face and following loading device collides and causes the damage of testpieces (such as loading device moves, and rudder face is motionless or rudder face
It is motionless to rotate loading device).We are separately mounted to following loading assembly monitor using optical electrical switch transmitting terminal with receiving terminal
The method at position provides testpieces effectively protection.
The content of the invention
The purpose of the present invention：The present invention provides a kind of photoelectric protection for aircaft configuration activity rudder face strength test and fills
It puts, being collided with rudder face with to solve in aircraft activity rudder face following loading loading device under abnormal conditions causes the destruction of testpieces to be asked
Topic.
The technical scheme is that：A kind of photoelectric protector for aircaft configuration activity rudder face strength test is
Optical electrical switchs, and transmitting terminal is separately mounted to the monitoring site of following loading device with receiving terminal, wherein, the transmitting terminal dress
Have an infrared light-emitting diode, receiving terminal be equipped with the corresponding light-operated triode of the light emitting diode, and receiving terminal triode is sent out
There are one relay, relay normally open contact is connected to Multi-channel fault detector input terminal, the output of tracer for emitter-base bandgap grading series connection
End connection Aero ST coordinated loading control systems.
When transmitting terminal adds 12V voltages, lumination of light emitting diode, and be coupled to receiving terminal, at this moment the three of receiving terminal
Pole pipe turns on, and the relay coil being in series therewith obtains electric, corresponding normally opened contact actuation.
When the light path of transmitting terminal and receiving terminal is obstructed by object, the relay electric-loss of receiving terminal, corresponding normally opened contact
It disconnects.
The solution have the advantages that：It is easy for installation, it can be matched with Multi-channel fault detector；It can solve aircraft
Testpieces protection problem during movable rudder face following loading；Protection zone is wide in range, fast response time, is protected immediately as long as light path is blocked
Shield；By 2 years, how long end-of-term examination was tested, stable and reliable for performance, ensure that experiment is smoothed out.
Optical electrical is switched first Application in aircaft configuration activity rudder face static(al), fatigue test by the present invention, is successfully solved
The problem of following loading safeguard protection.
Description of the drawings
Fig. 1 is photoelectric protector and Multi-channel fault detector and Aero ST coordinated loading control system totality composition figures；
Fig. 2 is optical electrical switch schematic diagram.
Wherein 1- photophores, 2- light-receiving devices, 3- protective devices, six road signal cables of 4-, 5- Multi-channel fault detectors, 6-
Aero ST coordinated loading control systems.
Specific embodiment
Below by specific embodiment, the present invention is described in further detail：
Referring to Fig. 1, it is that photoelectric protector and Multi-channel fault detector and Aero ST coordinated loading control systems are total
Body forms figure, and the transmitting terminal of six line protection devices (optical electrical switch) and receiving terminal are separately mounted to the prison of following loading device
Position is controlled, the output signal of six line protection devices is connected by cable with Multi-channel fault detector, the output of tracer
Signal is sent to Aero ST coordinated loading control systems.
Referring to Fig. 2, it is optical electrical switch schematic diagram, and when transmitting terminal adds 12V voltages, light emitting diode hair
Light, and it is coupled to receiving terminal, at this moment the triode ON of receiving terminal, the relay coil being in series therewith obtain electric so that phase
The normally opened contact answered is attracted.When the light path of transmitting terminal and receiving terminal is obstructed by object, the relay electric-loss of receiving terminal, accordingly
Normally opened contact disconnects.As needed, transmitting terminal and receiving terminal can be separately mounted to the monitoring unit of following loading device by we
Position.
Photoelectric protection operation principle：The relay normally open contact of optical electrical switch is connected to Multi-channel fault detector input terminal, tries
During testing, when the transmitting terminal for having any switch of optical electrical all the way is obscured by an obstacle with receiving terminal light path, optical electrical switch
Normally opened contact disconnects.It generates a relay output signal and is sent to tracer, simultaneously, tracer generates one
A relay exports signal and is sent to Aero ST coordinated loading control systems, makes experiment unloading/release.Simultaneous faults detector
Corresponding signal warning lamp is bright, the position that accurate positionin is facilitated to break down.
When mode in this way can solve movable rudder face following loading, the protection problem of testpieces.
This protective device can be not only servo-actuated, but also a detection faces can be monitored, and be expanded to testpieces
Protection zone.
