Experimental Research on Large Wind Tunnel Pressure Shell Using Acoustic Emission

Aiming at the Large wind tunnel pressure shell, during hydraulic test and increased pressure test, we carry on the acoustic emission monitoring for the purpose of structure integrity evaluation, flaw and flaw activity in reparative part monitoring. Some results with engineering practical meaning that the acoustic emission monitoring can be applied to the wind tunnel pressure shell in effect, and can evaluate and monitor the hydraulic test etc. in real-time are made out.
