Photomechanics Teaching Laboratory
Muti-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 methods 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.
