Abstract
This report is a study of a vibration control device using collision of mutual vibrators. The device consists of plural vibrators made of a cantilever beam and a tip mass. Transient response of the primary system is suppressed by vibrators because the vibration energy of the primary system is dissipated by collision of vibrators. Authors previously reported the vibration control device which uses collision of two vibrators. It was shown that the largest vibration control effect is acquired when the collision cycle of vibrators agrees with that of the primary system. In this report, vibration control effects in case of three or more vibrators are examined by simulation. In addition, the condition of vibrators which makes the vibration control effect largest is searched by DE method and the effect in compared.
