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 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. departmental bulletin paper 広島工業大学 2020-02 VoR application/pdf 広島工業大学紀要. 研究編 54 101 105 AA11599110 13469975 https://it-hiroshima.repo.nii.ac.jp/record/1111/files/research54_101-105.pdf https://it-hiroshima.repo.nii.ac.jp/records/1111 jpn publisher
