円環状振動体により励振される回転音場のシミュレーション Simulation of rotating sound field excited by flexural vibration rings 里信, 純 サトノブ, ジュン 高橋, 周平 タカハシ, シュウヘイ SATONOBU, Jun TAKAHASHI, Syuhei publisher sound filed traveling wave flexural vibration ultrasonic vibration application/pdf Rotating sound field excited by flexural vibration rings is used for some high power ultrasonic applications. To produce the traveling wave in the ring as the sound source, two standing waves excited both spatially and temporally orthogonal to each other should be superimposed in the ring using two or more transducers. However, excitation of the ideal distribution of the standing wave with multiple transducers, identical to the natural vibration mode of the ring, is difficult. This paper presents a numerical simulation of rotating sound field excited by flexural vibration rings, in particular, methods using two vibration rings, each with the standing wave, is discussed. 広島工業大学 2020-02 jpn departmental bulletin paper VoR https://it-hiroshima.repo.nii.ac.jp/records/1111 AA11599110 13469975 広島工業大学紀要. 研究編 54 101 105 https://it-hiroshima.repo.nii.ac.jp/record/1111/files/research54_101-105.pdf application/pdf 1.6 MB 2023-03-30
