概要

• 論文の詳細を見る

• The present report is concerned with a statistical research on the isolation of random vibration. A model system with two degress of freedom is taken up and its behaviour is analyzed when the random excitation is loaded on the foundation. The excitation is a stationary random force with an ideally withe spectrum over all frequencies. By investigating the properties of the mean square values of absolute accelerations and relative displacements, the optimum and the worst conditions for the suspension of the above-mentioned system were obtained, and a theoretical way of deciding how to suspend machnies was explained. Moreover the authors diagramed so that many values may be decided easily.
