| Abstract: | Bean bag damper (BBD) is a damper featuring discontinuous granular media with flexible constraints.The damping characteristics of BBD under different vibrations conditions are studied, and the effects of the exciting force, the damping, the natural frequency of the main system and the clearance between BBD and main system on BBD's damping efficiency are researched.It shows that BBD's damping efficiency increases with the exciting force and the natural frequency of the main system, but it can't increase obviously when the exciting force is large enough, and at the same time, the effects of the structural parameters of BBD on its damping efficiency are little. |
