Semi-active porous self-powered multi-dimensional shock absorber
The invention discloses a semi-active porous self-powered multi-dimensional shock absorber. The semi-active porous self-powered multi-dimensional shock absorber comprises two spherical cavities insideand outside, the two cavities are connected through spring devices, and the inner cavity and the outer cavity are filled with porous material. The inner spherical cavity is hollow, and a spherical liquid container is arranged in the center of the inner spherical cavity. A certain number of mass balls are arranged inside the inner cavity; the spherical liquid container in the center of the inner cavity is connected with the wall of the inner cavity through cylindrical channels; damping channels are arranged in the cylindrical channels, and the damping channels are externally wound with magnetexciting coils; and a piezoelectric power generating unit is arranged on the inner side wall of the inner cavity, and the piezoelectric power generating unit is connected in series with a controller and an electric energy extraction and storage unit to form a closed loop, and the controller and the electric energy extraction and storage unit are fixed to the outer wall of the cylindrical channels.The eight spring device, the eight cylindrical channels and eight piezoelectric power generating devices in vertical planes are evenly distributed. The vertical planes rotate around the central axisof a sphere, and the eight vertical planes are evenly distributed within 360 degrees of the horizontal plane.
本发明公开了一种半主动多孔自供能多维减振器，包括内部外部两个球形腔体，两腔体通过弹簧装置连接，内外腔体之间充满多孔材料。内部球形腔体中空，中心有球形液体容器。所述的内腔体内部有一定数量的质量球；所述的内腔体中心球形液体容器通过柱状通道与内腔体壁连接；所述的柱状通道内部置有阻尼通道，阻尼通道外部缠绕有励磁线圈；所述的内腔体内侧壁上设有压电发电单元，压电发电单元与固定在柱状通道外壁的控制器和电能提取与存储单元串联形成闭合回路。竖直平面内所述的弹簧装置，柱状通道和压电发电装置均匀分布有8个，此竖直平面绕球体中轴旋转，水平面360°内均布有8个。
