Semi-active electromagnetic type inerter damper and using method thereof
The invention provides a semi-active electromagnetic type inerter damper and a using method thereof.The semi-active electromagnetic type inerter damper comprises an outer shell, an inner shell, a ball screw pair system, an inerter system and an eddy current system, the inner shell can slide up and down in the outer shell, the bottom of the inner shell is connected with the ball screw pair system, and the inerter system is connected with the ball screw pair system; the inerter system is fixed to the bottom of the ball screw pair system, and the eddy current system is fixed to the bottom of the inerter system. When the main body structure vibrates, excitation energy is redistributed in the main body structure and the eddy current inertial mass damper, part of vibration energy of the main body structure is transmitted to an eddy current system and is converted into heat energy through eddy current to be dissipated, and the vibration effect of the main body structure is reduced; and the other part of energy is transmitted into the inerter system, and at the moment, the inertia mass can generate corresponding inertia force, so that the vibration response is attenuated.
本发明提供了一种半主动电磁型惯容阻尼器及其使用方法，包括外壳、内壳、滚珠丝杠副系统、惯容系统和电涡流系统，所述内壳可在所述外壳内上下滑动，所述内壳的底部与所述滚珠丝杠副系统连接，所述滚珠丝杠副系统的底部固定有所述惯容系统，所述惯容系统的底部固定有所述电涡流系统。本发明当主体结构振动时，激励能量在主体结构与电涡流惯性质量阻尼器中重新分配，将主体结构振动的一部分能量传递给电涡流系统，通过电涡流转换为热能耗散出去，降低主体结构的振动效应；另一部分能量传递到惯容系统中，此时惯性质量会产生相应的惯性力，从而使振动响应衰减。
