Аннотация
This research focuses on the influence of the ultrasonic flaw detection circuit on the ultrasonic emission. A software simulation and the super-exploration test are adopted. The characteristics of the transmitting circuit, the spike wave pulse generator and the square wave pulse generator are analyzed by simulating the pulse amplitude, the square wave pulse width and the transmitting pulse damping of the pulse generator. On the basis of simulations and experiments the fact that the best pulse effect relies on a reasonable coordination of pulse width and damping resistance is further verified. By using double-high-speed output power switch, appropriate adjustments on square wave pulse generator help to excite twice the charge voltage than the spike pulse generator can stimulate.
