Study on Acoustic CT Test system and It’s Application in the Detection of Dam Concrete

摘要：

Based on the analysis of existed dam CT test system, the acoustic CT test system collocated with giant magnetostrictive vibration source, serial ultrasonic reception transducers and ultrasonic instrument is presented. The giant magnetostrictive vibration source made up of rare earth giant magnetostrictive material is superior to other vibration sources and has many outstanding characteristics. Field test and application indicate that this system has the advantage of convenience and practicality. The system can solve the contradiction between spreading distance and testing precision when applied to detect dam concrete with acoustic CT.
