탄성파의 선택적 측정을 위한 비접촉 마그네토스트릭션 센서의 개발 및 실험적 검증
Development and Experimentation of a Non-Contact Magnetostrictive Sensor for the Elastic Wave Mode Selection
초록
Although the magnetostrictive sensors have received much attention in recent years. the investigations on the selection of a desired mode have not been reported. The purpose of this investigation is to present a technique to select a desired mode in a solid ferromagnetic cylinder using a non-contact magnetostrictive sensor. To achieve this goal. we propose new bias magnet configurations to select longitudinal and flexural waves. A few experimental results confirm the validity of the present investigation.
