The invention discloses a magneto-rheological composite working mode damping node and a damping seat, and belongs to the technical field of damping, and the damping node and the damping seat are characterized in that the damping node comprises a cylinder barrel, an inner partition plate is arranged in the cylinder barrel, the inner partition plate divides the interior of the cylinder barrel into two independent spaces, the two independent spaces are filled with magneto-rheological fluid, magnet yokes are arranged on the two sides of the inner partition plate, and the magnet yokes are arranged in the cylinder barrel. A plurality of coils are embedded in the side, away from the inner partition plate, of the magnet yoke and make direct contact with the magnetorheological fluid, the two ends of the cylinder barrel are each provided with a ball screw nut and a lead screw shaft which are used in a matched mode, the ball screw nuts and the lead screw shafts penetrate through and are rotationally connected, and the ball screw nuts are fixedly arranged on the cylinder barrel. According to the magneto-rheological composite working mode vibration reduction node and the vibration reduction seat, the situation that an existing magneto-rheological seat suspension structure mainly adopts a single shear mode to work, the structure size is large under the same output force, and application is inconvenient is overcome, large damping force can be provided under the condition that the space is limited, the overall structure is light, and the vibration reduction seat is convenient to use. And the lightweight design requirement is met.
本发明公开了一种磁流变复合工作模式减振节点及减振座椅,属于减振技术领域,其技术方案要点是,包括缸筒,缸筒内设有内隔板,内隔板将缸筒的内部分隔成两个独立空间,两个独立空间内均填充有磁流变液,内隔板的两侧均设有磁轭,磁轭远离内隔板的一侧嵌设有多个线圈,线圈直接与磁流变液接触,缸筒的两端均设有配套使用的滚珠丝杠螺母和丝杠轴,二者贯穿且转动连接,其中滚珠丝杠螺母固定设于缸筒上。该种磁流变复合工作模式减振节点及减振座椅克服了现有磁流变座椅悬架结构中主要采用单一剪切模式工作,相同出力下结构尺寸较大不便于应用的情况,能够在空间有限的情况下提供较大的阻尼力,且整体结构轻巧,满足轻量化设计要求。
