概要
- 論文の詳細を見る
An ultrasonic oscillator, which electromagnetically generates ultrasound by vibration of an iron plate in the alternating magnetic field, is newly proposed for high temperature use. Low Curie point for a normal transducer made of piezoelectric material is overcome by use of a ferromagnetic iron plate that has a high magnetic Curie point (1043 K). The strain or the amplitude of the plate that is oscillating in a standing wave mode for a given working frequency is measured with the aid of a fiber vibrometer. The effects of various process parameters on the sound pressure and the vibration mode are investigated. Decreased distance between the vibrating plate and an induction coil as well as a selection of resonant frequencies are significantly effective to get an increased strain or a strong sound for a given set of electromagnetic operating parameters.
