クラスタアクチュエーションを用いた振動試験用垂直加振台の基礎的検討

抄録

This paper considers the control method of a vibration table for a vibration test system. Recently, the vibration test with a high frequency range is required for aircraft parts. Difficulty in vibration test with high frequency range is the resonance frequency of the vibration table or the testing product. First, the cluster filtering and the cluster actuation used in the present study are brought together. Secondary, the result of the eigenvalue analysis was shown. It is for a simply supported rectangular plate to obtain the theoretical solution to verify the validity of the numerical analysis. Finally, the eigenvalue analysis for the four point supported rectangular plate was ascertained. In addition, the result of dynamic analysis was shown, and the vibration characteristic of the cluster actuation was clarified.
