Detailed Product Description

Photomechanics Teaching experimental system

Photomechanics teaching experimental system is a series of modern Photomechanics teaching instruments which was aborative studying by our company This system is consists of a TST1002 dual screen digital photoelasticity ,a TSSI1XP one-dimensional phase-shifting electronic speckle pattern interferometer (measure in-plane displacement ),a TSSI1ZP one-dimensional phase-shifting electronic speckle pattern interferometer (measure off-plane displacement ),a TSSSP phase-shifting electronic speckle pattern shearing interferometer.a DSC-1000 two-dimensional digital speckle correlation measurement .It can used to do the disc aperture stressed testing .girder pure bending testing .the stress concentration of hole edge testing ,Curvature girder circle curve measuring .Corner of  Curvature girders every section measuring , the disc displacement contour line measuring which around  clamped under uniform load, displacement  reciprocal theorem verification

This modern Photomechanics methos have been widely used in aviation, aerospace, shipbuilding, construction, water conservancy, metallurgy, nuclear power, bridges, life sciences, underground engineering, petroleum machinery and other fields,and also are the indispensable mechanics testing instruments of every  technical high ,secondary school and research institutes

Every kind of instruments which special design for mechanics experiment teaching can help the students deepen on the understanding of the book knowledge .and make the students understanding and master more modern mechanical testing techniques .so that the photomechanics can make a better actual service .

Experiment Item

dual screen digital photoelasticity

stress curve combinatorial experiment

Through the stripe of the curve area can count the grip magnitude ,thus deepen the understanding of stressed-curve combination stress distributing .

pure bending girder testing

Through watch the stripe distributing of the pure bending girder deepen the understanding of bending girder section stress distributing

the stress concentration of hole edge testing

Through the change of the stripe ,watch the phenomena of the stress concentration of hole edge

the disc aperture press testing

Through the isoclinals line watch the direction change of main stress

one-dimensional phase-shifting electronic speckle pattern interferometer measuring off-plane displacement

Can real-time observe the electronic speckle pattern interferometry fringes which Representative the off-plane displacement .equip stable three-point bending load device and the disc is loaded by uniform load (concentration) of the experimental apparatus. The entire system is stable and reliable, easy to adjust.

one-dimensional phase-shifting electronic speckle pattern interferometer measuring in-plane displacement .

Can real-time observe the electronic speckle pattern interferometry fringes which Representative the in-plane displacement .equip the stable cantilever load device and the disc is loaded by uniform load (concentration) of the experimental apparatus. The entire system is stable and reliable, easy to adjust.

phase-shifting shearing electronic speckle pattern interference test

Shearing electronic speckle pattern interferometer can be used for gradient measuring the off-plane displacement of object surface .compose the curve testing can measuring the corner distributing of the curve girder every section 

two-dimensional digital speckle correlation measurement testing

two-dimensional digital speckle correlation measurement can used to measuring two-dimension in-plane deformation of object surface . especially for large deformation measurements.with the girder curve testing can do the displacement  reciprocal theorem verification testing
