The effectiveness of chaos and fractal theory in analyzing ultrasonic nonlinear modulation signal was theoretically verified and a new way of using chaos and fractal theory in nondestructive testing is provided based on the simulation signal of ultrasonic nonlinear modulation effect. By constructing the simulation signal of modulation effect, the simulation signal with the chaotic character was found, and the nonlinear parameter and characteristic values of chaos theory were calculated to
