ダイラタント物質を用いたパッシブ・アダプティブ制振要素の検討

抄録

Adaptive vibration control is a method that changes vibration system characteristics according to the vibration level. To construct adaptive vibration control elements that do not require any external energy, called passive adaptive vibration control elements, we have proposed a method that uses nonlinear viscoelastic materials. This paper describes how we constructed these elements using dilatant materials and reports on the experiments we conducted with them. The results show that the vibration of mass supported by these elements is reduced when the vibration level is high. They also show that vibration is isolated by these elements when the vibration level is low.
