The invention discloses an active seat damping system. The active seat damping system comprises a first support, a second support, a rotary magnetorheological damper and at least two first telescopic supports. The first telescopic support is connected with the first support and the second support at the same time to adjust the relative distance between the first support and the second support. The first telescopic support comprises a scissor-type telescopic frame or a plurality of scissor-type telescopic frames which are sequentially connected end to end, the scissor-type telescopic frame comprises a first connecting rod and a second connecting rod, and the middle of the first connecting rod is rotationally connected with the middle of the second connecting rod; the rotary magnetorheological damper is installed at the rotary connecting position of the first connecting rod and the second connecting rod and used for providing damping when the first connecting rod and the second connecting rod rotate relatively. Compared with the prior art, the damping characteristic of the rotary magneto-rheological damper can be adjusted according to different actual road conditions, so that the damping performance of the seat is adjusted, active damping is achieved, and meanwhile vibration energy of the seat can be recycled.
本发明公开了一种主动式座椅减振系统,包括第一支架、第二支架、旋转式磁流变减振器和至少两个第一伸缩支架。第一伸缩支架同时连接第一支架和第二支架,以调整第一支架与第二支架的相对距离;第一伸缩支架包括一个剪式伸缩架或多个首尾依次相连的剪式伸缩架,剪式伸缩架包括第一连杆和第二连杆,第一连杆的中部与第二连杆的中部转动连接;旋转式磁流变减振器安装于第一连杆与第二连杆的转动连接位置,用于在第一连杆与第二连杆相对旋转时提供阻尼。相比于现有技术,本发明能够根据实际路况的不同对旋转式磁流变减振器的阻尼特性进行调整,从而调整座椅的减振性能,实现主动减振,同时可以对座椅振动能量进行回收。
