Displacement amplification inerter vibration absorption passive damping device
The invention relates to a displacement amplification inerter vibration absorption passive damping device, and belongs to the field of engineering vibration control. Comprising a ball screw assembly, an intelligent energy absorption-energy consumption assembly and a connecting assembly playing a connecting role. The inertia capacity effect can be adjusted by adjusting the size and position of the mass block according to the property of a to-be-installed structure, when the rotation peak acceleration of the mass block does not exceed a trigger limit, the mass block cannot make contact with the friction energy dissipation plate under the constraint effect of the spring, and at the moment, the device mainly absorbs energy; when the rotation peak acceleration of the mass block exceeds the trigger limit, the centrifugal force of the mass block is larger than the tension effect of the spring, the mass block makes contact with the friction energy consumption plate after sliding to the initial sliding-out gap, at the moment, the device starts to enter an energy absorption and consumption mechanism, and along with increase of the rotation speed, the larger the centrifugal force is, the larger the pressure of the mass block on the friction energy consumption plate is, and the energy consumption effect is improved. According to the invention, the vibration between structures caused by wind load, human-induced load, vehicle-induced load and earthquake load can be obviously reduced.
本发明涉及一种位移放大惯容吸振被动阻尼装置，属于工程振动控制领域。包括滚珠丝杠组件、智慧吸能‑耗能组件以及起到连接作用的连接组件。其可根据要安装结构的性质通过调节质量块的大小和位置来调节惯容作用的大小，当质量块的转动峰值加速度未超过触发界限时，质量块在弹簧约束作用下并不会与摩擦耗能板接触，此时装置以吸能为主；当质量块的转动峰值加速度超过触发界限时，质量块离心力大于弹簧拉力作用并沿滑到滑出初始间隙后，与摩擦耗能板接触，此时装置开始进入吸、耗能机制，并且随着转速的增大，离心力越大，质量块对摩擦耗能板的压力越大，耗能效果增加。本发明可显著减小风荷载、人致荷载、车致荷载和地震荷载引起的结构之间的振动。
