Description
Technical field
The present invention relates to a kind ofly determine that in the wind tunnel pressure measuring process of the test model surface pressure tap is connected the method for corresponding relation with pressure instrumentataion.
Technical background
Manometric test is one of test method basic in wind tunnel test, and purpose is for Vehicle Structure Strength computational analysis, analysis of flow characteristics and pneumatic design provide foundation, is exploratory flight device aerodynamic characteristic, the important means that obtains aerodynamic loading.At present, the main method of laying pressure tap at model surface that adopts of wind tunnel pressure measuring test, be sent to pressure transducer to model surface pressure by pressure tap and pressure measurement pipeline and measure.When multipoint pressure measure equipment such as adopting electric pressure scaner system or pressure transducer carries out manometric test, usually wish layout pressure tap as much as possible on pressure measuring model, in order to obtain the more detailed pressure distribution of model surface.Pressure tap as full scale model in one meter magnitude wind-tunnel is typically designed to 700 points, and in two meters magnitude wind-tunnel, the pressure tap of full scale model surpasses 1000 points usually.On model, hundreds of pressure tap need to be corresponding one by one with the measurement passage of electric pressure scaner system or pressure transducer by piezometric tube, could obtain fast and accurately the pressure distribution on model different characteristic section, for pneumatic research provides correct foundation.
At present, corresponding one by one in order to guarantee that model surface pressure tap and pressure instrumentataion measuring point are numbered, traditional method is:
When modelling, recording mechanism, component names and numbering, section title and numbering, the coordinate etc. that design and work out the model pressure tap (are called for short: model measuring point numbering);
Steel pipe number), and the corresponding relation of formation model measuring point numbering and steel pipe number (as: model measuring point numbering ← → steel pipe number) when mould processing, the pressure tap protective steel tube for drawing is numbered and (is called for short:;
Measurement channel number (determined by module No. and ozzle number combination while using the electric pressure scaner system, claim sensor number during the working pressure sensor, be called for short: measure channel number) to pressure instrumentataion;
The pressure measurement flexible pipe numbering that connects between pressure tap protective steel tube for drawing and pressure instrumentataion (is called for short: flexible pipe number);
When the pressure measurement flexible pipe connects the pressure tap protective steel tube for drawing, the annexation of manual record steel pipe number and flexible pipe number (as: steel pipe number ← → flexible pipe number);
When the pressure measurement flexible pipe connects pressure instrumentataion, the annexation of manual record flexible pipe number and pressure instrumentataion (as: flexible pipe number ← → measurement channel number);
With the model measuring point numbering of record ← → steel pipe number, steel pipe number ← → flexible pipe number, flexible pipe number ← → measure channel number to input respectively computing machine, arrange form final model measuring point numbering ← → measure the mapping table of channel number;
Check and verify the model measuring point to number ← → measure the mapping table of channel number, from model m section, the pressurization of n period, by the acquisition processing system image data, whether the checking mapping table is correct.
This tradition is determined the method for pressure tap corresponding relation, and its shortcoming is to rely on the correspondence of multiple numbering to make up to locate point position, and is loaded down with trivial details, time-consuming; Need repeatedly the manual record corresponding relation and input computing machine, time-consuming, fallibility; In dull, loaded down with trivial details working long hours, error probability is high.Along with increasing that pressure measurement is counted, this method will cause the sharp increase of time resource, demand of human resources, brings out the measuring point corresponding relation mistake that causes because of factors such as personnel's replacement, handwriting recognition, complicate statisticses and occurs.
