The Technology And Dynamic Simulation Research For Rotating Ultrasonic Probe Testing System

The High speed multi-probe ultrasonic testing system has been researched in this paper. Based on the generalized analysis to the development and tendency of domestic and abroad related technology, some ultrasonic testing methods for different defects were described in this paper. Simultaneously, the detailed principle of design and some essential technologies were presented.Water immersion ultrasonic testing method were used to in this system to test the bar. We use ultrasonic longitudinal wave and shear waves methods to test different defects in the bar. Water immersion focusing probes are used in this system, and the signal was transferred by rotary capacitors to the test instrument.High-speed rotary probes were used to test the defects by the bar detection system. And dynamic balance of the system is very important. A simulation model was established by Pro/Engineer. Then the simulation model was imported to ADAMS project software by using the interface module of Mech/Pro. The model was simulated by ADAMS. The problems that caused by the dynamic balance of the system will be discussed in this paper, and theoretical results will be provided for further design.
