Nonlinear vibration isolators with asymmetric stiffness
, 2012 A vibration source is commonly coupled to a receiving structure by a vibration isolator. A key trade-off in the choice of vibration isolator is the requirement for a wide frequency range of isolation without excessive static deflection.

Advanced Materials, EarlyView.ABSTRACT Accurately knowing the frontier orbital energies of the structurally disordered small‐molecule organic semiconductors that are used in optoelectronic devices such as organic light‐emitting diodes is required to rationally improve their performance. Here, we show that these energies can be deduced with a large accuracy from the peak energies of

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 ...
