Description
Technical field
The utility model belongs to wind tunnel experiment device field, more particularly to a kind of test chamber of porosity continuously adjustabe
Control device.
Background technology
In transonic wind tunnel experiment, wind tunnel wall interference problem is very serious.The property of subsonic speed wind tunnel wall interference and low
Fast wind-tunnel is similar, has been developed that some subsonic speed wind tunnel wall interference corrections are executed.When M >=1（M is Mach number）When, wind tunnel wall interference is main
It is due to that hole wall back wave has been got to caused by model.When Mach number is close to 1, hole can not be avoided with the method for shortening model
Wall back wave.The hole wall thousand of this property is disturbed, at present also without successful theoretical correction method.Various forms can only be used
Gas permeable wall (slotted wall, straight hole wall, inclined hole wall) as far as possible weaken hole wall back wave.But want to obtain in whole transonic region
To preferable wave dissipation effect, the porosity of hole wall must change and change with Mach number.At present, domestic and international many transonic speed wind
Hole employs this change porosity test section mostly.But subject matter present in it is as follows：
1. because the factor such as machining accuracy and the control error of servo control mechanism is inevitable, cause theoretical calculation and actual work
Make effect mismatch, although interference is improved, do not reach ideal effect；
2. test section moves plate and fixed board because processing technology and material limitation cause frictional force uneven, make later stage control fortune
Dynamic precision, stability etc. are barely satisfactory；
3. connecting cable between each component in scene etc. is not because use bus mode, but excessively redundancy, to the later stage
Maintenance brings inconvenience；
4. electric cylinders, motor, encoder use split-type structural, higher to installing space, installation specification, entirety is influenceed
The efficiency and precision of the project implementation.
Utility model content
The purpose of this utility model is exactly the defects of overcoming above-mentioned prior art to exist and deficiency, and provides a kind of opening and closing
Than the test chamber control device of continuously adjustabe.
The technical scheme of use is：
A kind of test chamber control device of porosity continuously adjustabe, mainly including multiple dynamic plates, multiple servo-electrics
Cylinder, wire, controller, host computer and fixed board, it is characterised in that：
The signal output part of controller is connected by signal input part of the wire respectively with multiple servo electric jars, in fixed board
On setting position offer multiple air vents, the quantity of air vent on the quantity of servo electric jar, the quantity of dynamic plate and fixed board

On.The power output shaft of each servo electric jar is fixedly connected with a corresponding dynamic plate, and the signal output part of host computer passes through
Wire signal input part corresponding with controller connects.
Variable porosity system polylith moves plate independence or the coordinated movement of various economic factors.It is required that can be with remote auto control, and possess experiment
The function of preceding preset percent opening.Monitoring means or safeguard measure are taken, anti-locking mechanism mutually extrudes.After the completion of said mechanism connection
Servo electric jar is controlled to change dynamic Board position by control system, so as to reach the purpose for changing fixed board porosity.
Host computer carries out various motion controls by controller to servo electric cylinders, main to complete giving for porosity positional parameter
Fixed, the dynamic Board position of display, the safe operation situation of the whole control system of monitoring, it is corresponding to make in alarm or failure generation
The work such as emergent management.
Controller can complete the motion required by various experiments with controlled motor, including given, the startup of servo parameter stop
Fastening position, spacing alarm etc., computer can obtain the information of controller in real time, to coordinate bulk testing process, then pass through drive
Dynamic device driving servo electric jar motion, makes plate move as needed, so as to realize that porosity changes.Industrial computer is as host computer
It is responsible for the inputs of parameter such as dynamic plate moving direction, distance and with the communication of controller and carrying out system-wide monitoring and management；
Controller is responsible for performing servo drive system reliable and effective scattered or combination control.
In control process, control system takes rational communication modes, communications protocol, dynamic plate motion is carried out accurate
Control, and timely can feed back current state by status information column and can be by the shaft position display field in main interface
Show each dynamic Board position, can not only ensure system real-time and stability and its effectively can independently realize complicated letter
The processing of breath and Optimal Decision-making.
Need to take monitoring means or safeguard measure, between anti-check plate and dynamic plate, move and sent out between plate and observation window in change
Raw collision, extruding.
The utility model has advantages below：
1. the new mechanical structure of design, match optimal electrically driven equipment, it is ensured that electromechanical perfect unification, by machining accuracy
It is reduced to the error of servo-drive system under the minimal error of requirement.
2. test section moves plate and fixed board passes through strict simulation calculation at the beginning of design, using new material and Precision Machining,
Ensure that dynamic plate, the contact surface of fixed board are uniform, frictional force is in allowed limits.
3. live electric part connection uses wire way, so as to ensure that field wiring workload substantially reduces, control
Process is simple, efficient.
4. electric cylinders, motor, encoder use integral structure, it is ensured that the performance of every electric cylinders uniformity to greatest extent,
In installation process, the requirement horizontal to installing space and installation is reduced, improves the efficiency in the project implementation process.
