1716 圧電素子を用いた適応型セミアクティブダンピング法 : ワイドバンド騒音制御への応用(J08-4 振動・騒音制御,適応構造,J08 知的材料・構造システム) 1716 Semi-active damping using piezoelectric device : Application to wide band signals

This paper presents an enhancement of the semi-passive structural damping technique known as Synchronized Switch Damping on Voltage source (SSDV). The original technique uses constant continuous voltage sources whereas the proposed enhancement uses adaptive continuous voltage source, which permits to fit the mechanical braking force resulting from the SSDV process to the vibration level. Experimental results under white noise solicitations are presented.
