Self-powered self-adaptive variable stiffness composite damping nonlinear energy trap
The invention provides a self-powered self-adaptive variable stiffness composite damping nonlinear energy trap. The self-powered self-adaptive variable stiffness composite damping nonlinear energy trap comprises a composite damping part, a nonlinear energy trap part, a control part and a self-powered part. According to the self-powered self-adaptive variable stiffness composite damping nonlinear energy trap provided by the invention, the stiffness of the nonlinear energy trap can be adjusted in real time by changing the temperature of the shape memory alloy spring; the stepping push-pull rod is controlled to change the magnetic conductance distance between the conductor plate and the permanent magnet so as to realize real-time damping adjustment of the nonlinear energy trap, and collision damping formed by collision between wrapped steel balls and liquid damping formed by liquid oscillation in the box body are combined to form composite damping so as to ensure the optimal vibration double-control effect. Oscillating liquid in the box body is used for driving the gear to rotate, the screw rod is connected to the permanent magnet direct current generator to supply power to a control center, and the energy supply stability under extreme disasters is guaranteed.
本发明提供了一种自供电的自适应变刚度复合阻尼的非线性能量阱，包括：复合阻尼部分、非线性能量阱部分、控制部分和自供电部分。本发明所提出的自供电的自适应变刚度复合阻尼的非线性能量阱，可通过改变形状记忆合金弹簧的温度实时调节非线性能量阱的刚度；通过控制所述步进式推拉杆改变所述导体板与所述永磁铁之间的磁导间距实现非线性能量阱的阻尼实时调节，结合包裹式钢珠间的碰撞形成的碰撞阻尼和箱体内的液体振荡形成的液体阻尼组成复合阻尼，以确保最佳的振震双控效果；利用箱体内振荡的液体带动齿轮旋转，通过螺杆连接至永磁直流发电机向控制中枢供电，保障了极端灾害下的供能稳定性。
