Ultrasonic Lamb Wave Measurement and Data Analysis System

Ultrasonic Lamb wave detection technology is an important, nondestructive testing technology for the damage of plate. In order to inspect the plate material nondestructively, an ultrasonic measurement system is investigated and the principle and structure of the system are described in this paper. The CTS-3000 instrument is used to excite and receive ultrasonic signal, which is delivered to computer through RS232 interface. Then the signal collected by the computer is analyzed with the 304 stainless steel as the experiment material. The results show that the proposed system can realize the measurement of ultrasonic with simple instrument structure and have great potential for future applications.
