Description
Technical field
The utility model relates to Young modulus fields of measurement, specifically, relates to a kind of young modulus measuring device based on equal thickness interference.
Background technology
Young modulus is a kind of basic mechanical parameter of material, is used for describing the physical quantity that deformation degree occurs when material is subject to External Force Acting.For common metal material, deformation quantity during External Force Acting is general less, so general measure instrument not easily Measurement accuracy.For the material of different geometries, the measuring method of Young modulus is different.Such as: bending method employing Hall effect measures the deformation of material, but hall effect sensor is difficult to adjustment, calibration; Dynamic method can be subject to the interference of extraneous vibration; Pulling method adopts optical lever the form that deformation quantity is reflected by light to be amplified, but the adjustment of this method bothers very much, also can introduce other errors in measuring process.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of young modulus measuring device based on equal thickness interference, and measuring accuracy is high, quick and easy for installation.
The utility model adopts following technological means to realize goal of the invention:
A kind of young modulus measuring device based on equal thickness interference, comprise reading microscope and laser instrument, it is characterized in that: the lower end of described reading microscope connects upper glass plate, the side, bottom of described upper glass plate is hinged with one end of lower-glass sheet, the other end of described lower-glass sheet is fixedly connected with sheet metal to be measured, described sheet metal to be measured connects spiral Constant load device, forms air gap layer between described upper glass plate and lower-glass sheet.
As the further restriction to the technical program, described spiral Constant load device adopts micrometer caliper digital display augmentor.
As the further restriction to the technical program, described micrometer caliper digital display augmentor comprises digital display dynamometer, Metallic rod and micrometer caliper, described digital display dynamometer is provided with digital display window, described digital display dynamometer one end connects described Metallic rod, the other end connects described micrometer caliper, and the upper end of described Metallic rod connects described sheet metal.
As the further restriction to the technical program, described sheet metal to be measured is circular or polygon.
Compared with prior art, advantage of the present utility model and good effect are: the utility model is by being fixed on sheet metal to be measured by lower-glass sheet, and upper glass plate and reading microscope are fixed, and form air gap layer between upper glass plate and lower-glass sheet; When sheet metal generation deformation to be measured, the variation in thickness of air gap layer causes equal thick interference fringe to change, and is accurately measured the deformation quantity of sheet metal by interference fringe.Effect afterburning is continuously realized by micrometer caliper digital display augmentor.The equal thick interference fringe of air gap layer accurately can react the change of air layer angle, thickness, so this measurement device precision is higher than original instrument.This device only needs glass sheet to be fixed can be measured by fixture and metal material to be measured, and overcome in traditional approach the complicated processes regulating Hall element, make experiment become simple to operation, efficiency is high, greatly saves experimental period.
