Semi-active negative rigidity multidimensional vibration damping device
The invention discloses a semi-active negative rigidity multidimensional vibration damping device. The semi-active negative rigidity multidimensional vibration damping device comprises an outer box body, wherein a tuned liquid damper, a negative rigidity mechanism and a magnetostrictive vibration generating unit are arranged inside the outer box body. The tuned liquid damper is a cylinder filled with damping liquid, the side surface of the cylinder is connected with a vibration absorption layer through a plurality of springs with one ends connected with rolling balls, the cylinder is arrangedon a plurality of metal balls, and the metal balls are arranged above a drum body. The negative rigidity mechanism is formed by the drum body and negative rigidity adjusting units radially arranged around the drum body; a giant magnetostrictive body is arranged at the bottom in the outer box body and connected with the drum body through a disc spring, and an induction coil and a permanent magnet are arranged around the giant magnetostrictive body from inside to outside to form the magnetostrictive vibration generating unit. An acceleration sensor is arranged at the bottom of the drum body andis connected with the magnetostrictive vibration generating unit, an electric energy storage and extraction unit, a controller and an excitation coil in series to form a closed loop.
本发明公开了一种半主动负刚度多维减振装置，包括一个外箱体，外箱体内部设有调谐液体阻尼器、负刚度机构和磁致伸缩振动发电单元。调谐液体阻尼器为装有阻尼液的圆筒，圆筒的侧面通过多个一端接有滚球的弹簧与吸振层相连，圆筒放置在若干金属球上，金属球放置在鼓形体上方。鼓形体与其四周呈放射状布置的负刚度调节单元构成了负刚度机构，在外箱体内底部设有超磁致伸缩体，与鼓形体之间通过碟簧相连，超磁致伸缩体的四周由内向外设有感应线圈和永磁体，构成磁致伸缩振动发电单元。鼓形体底部设有加速度传感器，与所述的磁致伸缩振动发电单元、电能存储与提取单元、控制器以及励磁线圈串联形成闭合回路。
