Magnetostrictive transducer and apparatus and method for monitoring structural health using the same |
摘要 |
A magnetostrictive transducer that generates a large shear horizontal (SH) wave useful for non-destructive testing of a plate member, and method and apparatus for structural health monitoring by using the magnetostrictive transducer. The magnetostrictive transducer includes: a magnetostrictive patch array comprising a plurality of magnetostrictive patches that have different radii of curvature, and have the same center of curvature when arranged on a plate member and form an overall fan-shape; a static magnetic field forming unit comprising two magnets that are respectively installed on both sides of the magnetostrictive patch so that a magnetic field is formed in parallel to an arc direction of the magnetostrictive patch; and a dynamic magnetic field forming unit comprising a wound coil comprising a plurality of curved portions. |
