Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To realize a method for detecting a surface damage capable of accurately detecting a type and a depth of the surface damage even in the case of varying a surface wave generating efficiency and its propagation efficiency. SOLUTION: A pulse voltage transmitted from a pulse transmitter 3 is converted into a ultrasonic wave by a transmitting ultrasonic probe 4, and converted into a surface wave at a surface of a thick steel sheet 1 through a contact medium. The surface wave propagating a predetermined range is received by a receiving ultrasonic probe 5, a vibration is converted into an electric signal, and transmitted to a receiver 6. The receiver 6 sends an RF waveform corresponding to the transmitted wave used for detecting the damage from the received electric signal to a spectrum analyzer 7. The analyzer 7 Fourier-transforms the transmitted RF waveform to obtain a power spectrum of a frequency axis. These data are sent to a calculator 8. The calculator 8 estimates the type and the depth of the surface damage.  If the calculator 8 decides the presence of the damage, the calculator 8 operates to send the depth and the type to an output unit 9.

However, the brush 12 makes line contact with holder, the brush 12 is not separated from the contact surface of the commutator 17, but can sufficiently follow the irregular movement of the contacting surface of the commutator 17 while the rotor 4 rotates at the high speed. Therefore, no discharge are occurs from the lower end of the brush holder 11a.
