摘要： A nondestructive inspection apparatus includes a vibrating section 11 which is adapted to be placed in pressure contact with a surface of a measuring object 16 for generating an acoustic elastic wave W, a receiving section 12 for receiving a reflected wave, a pushing mechanism 13 for pushing the vibrating section and the receiving section against the measuring object, a pushing force measurement section 14 for detecting pushing forces Fa, Fb during vibration, a vibration control section 10 for driving the vibrating section, and a reception signal processing section 15 for determining the internal defect based on a reception signal R. The reception signal processing section includes a reflection energy calculation section for calculating a reflection energy level due to elasticity vibration of the measuring object, a reflection energy correction section for normalizing the reflection energy level by the pushing force to calculate a correction value; and an internal defect determination section for detecting the internal defect based on the correction value. With this arrangement, the absolute reflection energy level of the reflected wave is determined through comparison, thereby making it possible to improve the evaluation accuracy of the internal defect to a substantial extent.

摘要： An acoustic wave transmission system comprises an acoustic wave generating metal tubular member for converting information about the bottom of a borehole, which is obtained by a bottom hole sensor, into an acoustic wave. The acoustic wave generating metal tubular member includes a acoustic wave generating mechanism having at least a magnetostrictive oscillator which is mounted in a recess formed in an outer wall of the acoustic wave generating metal tubular member, and on which a compressive load is imposed by means of a pre-load mechanism using a vise. The magnetostrictive oscillator is constructed of a stack of thin plates each made of a metal magnetostrictive material having a property of increasing its dimensions when magnetized, the thin plates being bonded together by a heat-resistant adhesive. The magnetostrictive oscillator can thus have a buckling strength large enough to resist the compressive load imposed thereon by the pre-load mechanism and a stress due to a strain caused in itself. The acoustic wave generating metal tubular member further includes an excitation current supplier for supplying either a rectangular, sinusoidal, or triangular alternating excitation current modulated with the information about the bottom of the borehole and having a frequency that is half the carrier frequency of the acoustic wave, or a series of excitation pulses modulated with the information about the bottom of the borehole and having a pulse repetition rate that is equal to the carrier frequency of the acoustic wave, to an excitation winding wound around the magnetostrictive oscillator.

摘要： A nondestructive testing apparatus is provided with a wave transmitter by a metal-based magnetostrictive vibrator, a magnetically excited current feeding device for feeding the magnetically excited current to the magnetostrictive vibrator, a wave receiver for detecting an acoustic elastic wave propagating through the measurement object, a filter for extracting a signal in a target frequency band to be measured, and an automatically amplifying rate controlling function-equipped amplifier for automatically controlling the amplifying rate so as to obtain a given magnitude amplitude regardless of the magnitude of the reflection wave or the transmission wave detected by the wave receiver, which constitute a feedback loop. The apparatus is further provided with a signal processor for processing the signal detected by the above-described wave receiver, and a display device for displaying the process result obtained by the signal waveform detected by the above-described wave receiver or the above-described signal processor.
