Description
Technical field
The invention belongs to high-low-temperature environmental testing field, be particularly related to the acceleration measurement device of pipeline structure.
Background technology
Because the working environment of aerospacecraft pipeline on arrow is general all very harsh, under being often in the environment of high temperature or low temperature, therefore, need to carry out acceleration analysis to pipeline while simulating line temperature when ground experiment.The resonant frequency of sensor and erection support assembly directly affects the highest frequency that sensor can be surveyed, sensor connected mode in traditional pipeline structure acceleration analysis: magnetic-type, adhered, bolt connection type is fixed.Namely magnetic-type sensor connected mode utilizes the suction-operated of magnet to connect, and intensity is low and have requirement to material, under only can be used for the less environmental baseline of the structural vibration magnitudes such as mode; Namely adhered sensor connected mode utilizes bonding agent to be directly bonded in tube wall, for under the environmental baseline that temperature conditions is not harsh, the thin-wall construction of pipeline responds greatly in vibration processes, and distortion is violent, sensor bonding strength cannot ensure compact siro spinning technology, is easy to drop; Bolt connection type sensor connected mode then needs to bore threaded connection hole on testpieces surface, and pipeline structure is thin-wall construction, can not punch in surface, so above-mentioned method of attachment is all difficult to when pipeline structure is tested directly realize.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide pipeline structure sensor fastening device and acceleration measurement device, ensure that connection is fastening, sensor measurement data is accurate.
For solving the problems of the technologies described above, inventing a kind of pipeline structure sensor fastening device, having comprised sensor, bearing, ring texture, bearing is fixed on outside ring texture, and sensor is connected on bearing, and ring texture is enclosed within pipeline structure, two ends are fixedly connected, and inner and pipeline fits tightly.
As a further improvement on the present invention, in ring texture, lay heat insulation layer, while guarantee anatomical connectivity is fastening, prevent low temperature (high temperature) to the infringement of sensor.
As a further improvement on the present invention, during high temperature conduit test, heat insulation layer is made up of asbestos cloth, and be made up of felt during cryogenic pipe test, asbestos cloth and felt heat insulation layer also play the effect of electrostatic between isolated sensor and pipeline structure.
As a further improvement on the present invention, ring texture is made up of aluminum alloy materials, because its density is little, bring unnecessary additional mass to pipeline as far as possible less, and because pipeline is mostly stainless steel structure, its rate of heat dissipation of aluminium alloy, higher than stainless steel, can be delivered to the temperature of sensor connecting surface further near normal temperature.
For solving the problems of the technologies described above, also invented a kind of acceleration measurement device of pipeline structure, using foregoing pipeline structure sensor fastening device orthogonal three-dimensional on bearing at least to offer 1 connecting hole.
As a further improvement on the present invention, owing to the many strain measurement lines of cloth on pipeline structure surface, trough is set in ring texture, strain line is evenly arranged in trough, fixes, and ensure individual layer winding displacement.
As a further improvement on the present invention, the outside of ring texture comprises foam insulation, and bearing is exposed outside foam insulation.
As a further improvement on the present invention, on bearing, orthogonal three-dimensional offers 5 connecting holes, connect 5 sensors at most simultaneously, the acceleration analysis that three axles are multidirectional can be realized, both the measurement of three directional accelerations had been solved, also make at specific position, the place being not easy to sensor layout has other position to select.
As a further improvement on the present invention, meet pipeline structure complexity, cannot reach an agreement with test direction, the glass bloom of first mounting strap angle on connecting hole, direct connecting sensor on glass bloom, guarantor is to reaching an agreement.
Before measurement, many strain measurement lines can be arranged on the surface at pipeline structure, by it uniformly across trough, and ensure individual layer winding displacement; Then, bearing is arranged on outside ring texture, be enclosed within outside pipeline structure, two ends are fixed, guarantee that fixing half-turn inwall and pipeline fit tightly, after having connected, carry out foamed heat insulation at whole test pipeline outside surface, make sensor erection support exposed outside foaming layer, sensor is connected with connecting hole.During measurement, mount sensor, put into acceleration environment by the connecting hole of different azimuth, the test carrying out data receives.
The present invention is after repeatedly count and check, the acceleration measurement device of design has good dynamics transmission characteristic, make its one class resonant frequency higher than the frequency range of pipeline structure vibration test, therefore, it is possible to it is consistent with the data height gathered when being directly pasted on tube wall to ensure that sensor is arranged on the data that acceleration measurement device gathers.
Therefore Advantageous Effects of the present invention is: (1) solves in pipeline test and conventional sensors cannot be used to be fixedly connected with problem; (2) multiple sensor can be arranged, realize the multidirectional acceleration analysis of three axles; (3) the sensor mounting under pipeline complex situations is realized.
