回転音場を形成する超音波振動系の設計に関する研究 ―ねじり・たわみ複合振動子で駆動する振動系の設計― Design of an ultrasonic vibration system for generating rotating sound field —Design with torsional-flexural composite transducers— 里信 純, 高橋 周平, 越智 堅敦, Jun SATONOBU, Syuhei TAKAHASHI, Kento OCHI sound filed, traveling wave, torsional vibration, flexural vibration, composite transducer, ultrasonic vibration application/pdf Rotating sound field excited by flexural vibration disk is used for some high-power ultrasonic applications. To produce the traveling wave in the disk as the sound source, two standing waves excited both spatially and temporally orthogonal to each other should be superimposed in the disk. This paper presents a design of the system driven with torsional-flexural composite Langevin transducers and an advantage of the system with four transducers for traveling wave excitation. 広島工業大学 jpn departmental bulletin paper VoR https://it-hiroshima.repo.nii.ac.jp/records/2000018 AA11599110 1346-9975 58 57 62 https://it-hiroshima.repo.nii.ac.jp/record/2000018/files/research58_57-62.pdf application/pdf 1.5 MB 2024-08-28
