Multi-stable nonlinear energy trap device
The invention relates to a multi-stable nonlinear energy trap device. The device comprises a base bearing plate (1), a linear guide rail (2), an oscillator supporting plate (5) and a linear bearing (3) which are connected with an external main structure, and an oscillator (11) is connected with the oscillator supporting plate (5) through bolts; a pair of original long tension-compression long springs k1 (6) with long guide pipes (7) and a pair of original long tension-compression short springs k2 (8) with short guide pipes (9) are symmetrically arranged on the two sides of the oscillator (11)in the direction perpendicular to the linear guide rails (2); the lengths of the two pairs of springs at the balance position are different, and the included angles between the two pairs of springs and the oscillator are also different; and meanwhile, the two ends of an magnetorheological damper (4) are connected with the oscillator (11) and a baffle (12) through pin shafts (10) respectively. Compared with an existing nonlinear energy trap damping device, the structure has the advantages of being wider in vibration absorption frequency, better in robustness, better in energy consumption effectand the like.
本发明涉及一种具有多稳态的非线性能量阱装置，该装置包括有与外部主结构相连的基底承台板(1)、直线导轨(2)、振子托板(5)、直线轴承(3)，并使用螺栓将振子(11)与振子托板(5)相连；将一对带有长导向管(7)的处于原长拉压长弹簧k(6)、一对短导向管(9)原长拉短压弹簧k(8)对称布置于振子(11)两侧与直线导轨(2)相垂直的方向上；并且这两对弹簧处于平衡位置的长度不同与振子之间的夹角也不相同；同时，磁流变阻尼器(4)的两端采用销轴(10)分别与振子(11)和挡板(12)相连接。该结构与现有的非线性能量阱减振装置相比，具有吸振频率更宽、鲁棒性更好以及耗能效果更佳等优点。
