Title:
VIBRATION ENERGY ABSORBER
Document Type and Number:
WIPO Patent Application WO/2008/072325
Kind Code:
A1
Abstract:
A vibration energy absorber (1) comprises a reciprocating member (2) reciprocating
freely between positive and negative maximum displacement positions D±max
with respect to the origin position O in the H direction, a damping force generating
means (3) generating a damping force R against reciprocating motion of the reciprocating
member (2) in the H direction, and a means (4) for controlling the damping force
generating means (3) to generate a predetermined damping force R during forth
motion of the reciprocating member (2) in the H direction in the respective H-direction
motions from the positive and negative maximum displacement positions D±max
to the origin position O, and controlling the damping force generating means
(3) not to generate the damping force R substantially in the respective H-direction
motions from the origin position O to the positive and negative maximum displacement
positions D±max following the movements in the H direction.
