Validation of a Probabilistic Mathematical Model for Soybean Seed Separation in a Gravity Column
Сельскохозяйственные машины и технологииIn mathematical models of the separation process in a gravity column, the coefficient of bar vibration is frequently disregarded as seeds and impurities move along the curved surface of the gravity column, which, in turn, affects the quality of ...

Vibrations of the reed and the air column in the bassoon
Journal of the Acoustical Society of Japan (E), 1989 Reed vibrations and pressure variations in the reed have been observed at the same time for the lowest note of a bassoon artificially blown. For comparison, the observations have been performed also for a cone simulating the bassoon and for a bassoon without tone holes. Behaviors of the bassoon and the bassoon-like systems artificially blown are fairly

Vibration of an Engine Column and a Double Bottom
JOURNAL OF THE MARINE ENGINEERING SOCIETY IN JAPAN, 1970 内燃機関架構の横振動によるトラブルは, 過去かなりの例が報告されているが, 機関付属物に悪影響をおよぼすという直接的被害のほかに, 船体の水平, ねじり振動を誘起したり, 局部振動の原因となったり, 設計者にとっては一つのやっかいな問題である.とくに最近のように船体機関が大形化してくると, 固有振動数は低下してくるため, 常用回転数付近で共振する場合が多くなると考えられる.本論文では, この問題に対する研究の現況を紹介した.まず実機測定により, 架構の振動特性をは握し, 固有振動数が基礎の剛性により大きく左右されることを示した.つぎに, 架構を集中質量系のはりおよび等価的な平面骨組構造系に置換して, マイクレスタッドの方法およびマトリクス法により ...
