It is detachable, it is easy to quick-replaceable and recovery after destroying.
Preferably, the diameter range of spheric granules is 1~30mm to one kind as the present embodiment, and uniform grain composition makes
Intergranular gap is smaller, is advantageous to energy by collision, while can reduce the resonant frequency of system, because energy dissipation coefficient increases with particle diameter
Reduce greatly, excessive grain diameter can make it that the probability increase of harmful collision occurs in vibration processes for structure, therefore preferably use
The less particle of diameter, damping effect is more preferable when small diameter particles are more.Amounts of particles is more, and granular pile height is higher,
The energy of collision and frictional dissipation is more under same acceleration, but the distance of particle to bottom surface on inner chamber body 4-6 is not nearer
It is better, when in horizontal positioned multistage composite damper, inner chamber body 4-6 the superiors' particle to inner chamber body inwall ultimate range for maximum
At 1.6~3.6 times of spherical particle diameters, damper response is minimum, and damping effect is preferable.
