High-order energy consumption enhanced nonlinear energy trap
The invention discloses a nonlinear energy trap with enhanced high-order energy consumption. The nonlinear energy trap is composed of a buckling restrained spring, an oscillator box body, a friction sliding rail, a restraining support and a bottom plate. The high-order energy consumption enhanced nonlinear energy trap, the friction sliding rail and the constraint support are fixedly arranged on the bottom plate, and the vibrator box slides along the friction sliding rail. The buckling restrained springs are arranged in pairs and are symmetrical to the vibrator box body, one end of each buckling restrained spring is fixed on the bottom plate through a restraining bracket, and the other end of each buckling restrained spring is connected with the side edge of the vibrator box body; buffer materials are arranged on the inner wall of the vibrator box body and filled with collision particles. Compared with the prior art, after the vibration reduction system is installed on a main body structure, vibration energy of the main body structure can be absorbed on a wide vibration reduction frequency band through a target energy transfer mechanism, the vibrator stroke is greatly reduced, meanwhile, the excellent rapid energy dissipation capacity is achieved in a high-order frequency band, and therefore the excellent vibration control effect is achieved.
本发明公开了一种高阶耗能增强的非线性能量阱，该装置由屈曲约束型弹簧、振子箱体、摩擦滑轨、约束支架和底板组成。所述高阶耗能增强的非线性能量阱，摩擦滑轨和约束支架固定设置于底板上，振子箱体沿摩擦滑轨滑动；屈曲约束型弹簧成对设置，且对称于振子箱体设置，屈曲约束型弹簧一端通过约束支架固定于底板上，另一端与振子箱体侧边连接；振子箱体内壁设有缓冲材料并内填碰撞颗粒。与现有技术相比，本发明的减振系统安装于主体结构上之后，能够通过靶向目标能量传递机理在较宽减振频带上吸收主体结构的振动能量，且振子行程大大降低，同时在高阶频段具有优秀的快速耗能能力，从而获得卓越的振动控制效果。
