A guided wave mechanism for acoustic emission monitor(ing) of uniaxial extension high temperature creep

The utility model discloses a guided wave mechanism for acoustic emission monitor(ing) of uniaxial extension high temperature creep has solved the acoustic emission in the unable problem of using in metal high temperature creep damage field. Concrete anchor clamps mechanism and the coupling mechanism down of including, lower anchor clamps mechanism, including anchor clamps main part, wedge pincers, wedge groove, tensile pole and handle, the twist grip drives tensile pole and reciprocates, and messenger's wedge pincers are hugged closely the wedge groove face and are slided from top to bottom, the locking test piece, coupling mechanism, including down connecting piece and double-end threaded connection axle, double-end threaded connection axle will descend the anchor clamps mechanism to be fixed in on the stretcher test bench, placing acoustic emission sensor down in the connecting piece, setting up the couplant between sensor and tensile pole, the sensor is transfered through tensile pole to the transient state stress wave of creep process release, but rotating double-end threaded connection axle jam sensor. Mechanism structure is simple for this guided wave, simple to operate, and signal attenuation is little, and temperature damping is fast to acoustic emission monitor(ing) for the high temperature creep process provides safeguard.
