Mounting structure and mounting method of the acoustic wave generator and magnetostrictive oscillator

摘要

An elastic wave generator capable of generating and injecting an arbitrary stress wave (elastic wave) in a large structure is realized. The excitation Coyle 36 is formed by laminating a magnetostrictive plate of a metal based crystal structure having a positive strain characteristic and having a directionally long change in length, and a magnetostrictive oscillator 34 having a rigid winding wound by the excitation Coyle, and the direction in which the length of the magnetostrictive oscillator changes, and the direction of change The flow of the magnetostrictive oscillator due to the excitation of the exciting Coyle having a pair of supporting surfaces 1A which shrink fit with one end surface 34a and the other end face 34B intersecting with the direction in which the length of the magnetostrictive oscillator changes and the direction of which the length of the magnetostrictive oscillator changes; There is provided a nonmagnetic oscillator support in which both of the support surfaces are directly received from both ends of the magnetostrictive oscillator.
