| titleOfInvention | Transducer capable of generating and measuring torsional waves, and an abnormal diagnosis device and method using the same |
| abstract | The present invention relates to a non-destructive inspection method and apparatus for inspecting whether a structure has a structural defect, and specifically, generates a torsional wave on an axis, beam, and pipe having an arbitrary cross section including a circular shape, and reflects it back. The present invention relates to a method for diagnosing abnormalities of a structure and a device therefor capable of determining the presence or absence of a defect and the location of the defect by analyzing a torsion wave. According to the present invention, a plurality of ferromagnetic strips are attached obliquely at a certain angle, such as 45 ° with respect to the center along the circumference of a rod member having a predetermined length, the insulator disposed around the strip and wound around the insulator Provided is a magnetostrictive transducer including a true coil, wherein the strip generates a torsional wave in the rod member by a magnetostrictive effect when a current is supplied to the coil, and an abnormal diagnosis apparatus and method using the same are provided. According to the present invention, torsionally induced ultrasonic waves can be stably generated and measured using a magnetostriction phenomenon even for a pipe made of a nonmagnetic material such as aluminum. In addition, unlike conventional methods, the torsion wave can always be generated regardless of the magnitude of the current applied to the coil, so that the repeatability is high, and the strip does not need to be pre-magnetized. It is much better than the conventional transducer at.n n n n Torsional wave, nondestructive testing, magnetostrictive transducer, ferromagnetic material |
