Description
Technical field
The invention belongs to exploration field, especially relates to a kind of high stability displacement measuring device.
Background technology
Displacement measurement is a critically important link in engineering structure test, by test structure about position position
Move, it will be appreciated that its stress distribution situation under load action, internal force situation, the performance so as to solution structure and bearing capacity
Deng.Therefore, generally it is required in structural test carrying out displacement measurement.In structured testing, relatively common displacement
Test mainly has:
1st, resistive displacement test.Under normal circumstances, resistive displacement is generally adopted for short-term research test indoors
Test.This displacement measurement, the impact to test specimen is little, can be good and cheap with automatic data collection.But, this displacement measurement is easy
Affected by environment, have high demands simultaneously for pasting for displacement piece, Long-term Displacement test can not be carried out.
2nd, amesdial displacement measurement.Displacement measurement for large-scale component short-term is usually taken amesdial displacement measurement.This
The method of kind is simple to operate, repeatable utilization, while not affected by the interference of electromagnetic field.But, the degree of shining upon can affect to survey
Examination data, on digital independent, error is larger and it is necessary to nearby observe, and reads data.Generally, 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 directly read, need through conversion.
4th, optical fiber (grating) displacement transducer.Optical fiber (grating) displacement transducer sensitivity and high resolution, response speed
Hurry up, small volume, lightweight, flexibly, outward appearance can be customized simple structure, easy for installation, electromagnetism interference, electric insulation, corrosion-resistant
The remote detection to measured signal is easily realized, realizes telemtry net and optical fiber sensor network, 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, produces, by the coil for encapsulating, the output signal for having good linear relation with relative displacement, realizes relative displacement measurement.It has
There is high precision, the good feature of dynamic characteristic, it is 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
During actual amount displacement, need the two ends of displacement meter are separately mounted to the position of two fixations as needed, with both measurements
Between relative displacement.Installing displacement meter in structured testing at present mainly has following three kinds of methods:
(1) displacement meter is fixed on a measuring point, and measuring staff end is connected with another measuring point by extended line.This erection side
Formula is usually used in measuring the relative displacement in longer gauge length;
(2) displacement meter is fixed on a measuring point, and measuring staff end is connected with the disc-shaped target plate for being fixed on another measuring point
Touch.
(3) displacement meter is fixed on a measuring point, and measuring staff end is directly put down with another measuring point place vertical with measuring staff
Face contacts.
As, in actual experiment, measuring point also can occur small displacement in the non-measurement free degree, and these displacements can be made
Become displacement meter or Target Board in the non-motion measured in the free degree.The method of above-mentioned three kinds of installations displacement meter all can be because of these
Move and error is introduced on the free degree is measured, cause the inaccurate of measurement.
