Description
Technical field
The invention belongs to exploration field, especially relates to a kind of exploration 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, thus the performance of solution structure and bearing capacity
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, 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 of 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, is not affected by the interference of electromagnetic field simultaneously.But, the degree of shining upon can affect to survey
Examination data, on digital independent error larger and it is necessary to nearby observe, read 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, structure simple and flexible, outward appearance can customize, easy for installation, electromagnetism interference, electric insulation, corrosion-resistant
Easily realize the remote detection to measured signal, realize telemtry net and optical fiber sensor network, good stability, can be used for seeing for a long time
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 utilizes differential transformer former
Reason, produced by the coil of encapsulation has the output signal of 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, to measure the two
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 being fixed on another measuring point
Touch.
(3) displacement meter is fixed on a measuring point, put down vertical with measuring staff that measuring staff end is directly located with another measuring point
Face contacts.
Because, in actual experiment, measuring point also can occur small displacement on non-measurement degree of freedom, and these displacements can be made
Become displacement meter or Target Board in the non-motion measuring on degree of freedom.The method of above-mentioned three kinds of installation displacement meters all can be because of these
Move and introduce error on measuring degree of freedom, cause the inaccurate of measurement.
