Description
Technical field
The invention belongs to exploration field, more particularly, to a kind of bidirectional displacement measurement apparatus.
Background technology
Displacement measurement is a critically important link in engineering structure experiment, by test structure about position position
Move, it will be appreciated that its stress distribution situation, internal force situation under load action, so that the performance and bearing capacity of solution structure
Deng.Therefore, generally it is required for carrying out displacement measurement in structural test.In structured testing, relatively common displacement
Test mainly has：
1st, resistive displacement test.Under normal circumstances, generally resistive displacement is used for short-term research experiment indoors
Test.This displacement measurement, influence to test specimen is small, can be good and cheap with automatic data collection.But, this displacement measurement is easy
Influenceed by environment, require height simultaneously for pasting for displacement piece, Long-term Displacement test can not be carried out.
2nd, amesdial displacement measurement.The displacement measurement short-term for large-scale component is usually taken amesdial displacement measurement.This
The method of kind is simple to operate, repeatable utilization, while not influenceed by the interference of electromagnetic field.But, the degree of shining upon can influence to survey
Examination data, error is larger on digital independent and it is necessary to nearby observe, and reads data.Generally, the phase in data acquisition
To relatively difficult.
3rd, thread-vibration type device for sensing displacement.Thread-vibration type device for sensing displacement is usually taken for outdoor long-term displacement measurement.Should
Sensor performance is stable, easy for installation, can be used for long term monitoring, but, price is of a relatively high, and volume is larger, is easily touched
Hit, simultaneous displacement data can not be directly read, it is necessary to by conversion.
4th, optical fiber (grating) displacement transducer.Optical fiber (grating) displacement transducer sensitivity and high resolution, response speed
Hurry up, small volume is lightweight, flexibly, outward appearance can be customized simple structure, easy for installation, it is electromagnetism interference, electric insulation, corrosion-resistant
The remote detection to measured signal is easily realized, telemtry net and optical fiber sensor network is realized, good stability can be used for long-term sight
Survey.But this displacement meter is mainly used in the relative displacement between 2 points of measurement small distance.
5th, linear differential transformation type displacement sensor.Linear differential transformation type displacement sensor is former using differential transformer
Reason, the output signal for having good linear relation with relative displacement is produced by the coil for encapsulating, and realizes that relative displacement is measured.It has
There is high precision, the characteristics of dynamic characteristic is good, be widely used in the every field such as Aero-Space, machinery, building, metallurgy.
In structured testing, linear differential transformation type displacement sensor is the class displacement meter being most widely used.But
, it is necessary to the two ends of displacement meter are separately mounted into two fixed positions as needed during actual amount displacement, to measure the two
Between relative displacement.Installing displacement meter in current structured testing mainly has following three kinds of methods：
(1) displacement meter is fixed on a measuring point, and measuring staff end is connected by extended line with another measuring point.This erection side
Formula is usually used in measuring the relative displacement in gauge length more long；
(2) displacement meter is fixed on a measuring point, and measuring staff end connects with the disc-shaped target plate for being fixed on another measuring point
Touch.
(3) displacement meter is fixed on a measuring point, measuring staff end directly with it is vertical with measuring staff flat where another measuring point
Face is in contact.
Because in actual experiment, measuring point can also occur small displacement in the non-measurement free degree, and these displacements can make
Into the motion of displacement meter or Target Board in the non-measurement free degree.The method of above-mentioned three kinds of installations displacement meter all can be because of these
Move and introduce error on the free degree is measured, cause the inaccurate of measurement.
