Inertial mass damper of lead screw flywheel mechanism
The invention belongs to the field of dampers, and particularly relates to an inertial mass damper of a screw flywheel mechanism, comprising a first ball screw inerter structure; the second ball screw inerter structure is mounted on the first ball screw inerter structure, and the second ball screw inerter structure is mounted on the second ball screw inerter structure; and the front end structure is mounted on one side of the first ball screw inerter structure. When energy input is small, force provided by the device for the structure is only the sum of elastic restoring force and small equivalent inertia force, and compared with the prior art, a traditional ball screw inertia mass damper usually depends on huge inertia force generated by a flywheel to achieve the energy absorption and shock absorption effects of the structure. The huge inertia force possibly has adverse effects on the structure, the load and vibration of the structure are increased, when the energy input is large and the inner piston reaches the deformation limit, the first ball screw inerter structure works, and then the needed equivalent inertia force is provided.
本发明属于阻尼器领域,具体涉及一种丝杠飞轮机构的惯性质量阻尼器,包括第一滚珠丝杠惯容结构;第二滚珠丝杠惯容结构,所述第二滚珠丝杠惯容结构安装在所述第一滚珠丝杠惯容结构上;前端结构,所述前端结构安装在所述第一滚珠丝杠惯容结构的一侧。当能量输入小时,本装置为结构提供的力仅为弹性恢复力和较小的等效惯性力之和,相比之下,传统的滚珠丝杠惯性质量阻尼器常常依赖于飞轮产生的巨大惯性力来实现结构的吸能减震作用,这种巨大的惯性力可能会对结构产生不利影响,增加结构的负荷和振动,当能量输入较大时,内活塞达到变形极限时,第一滚珠丝杠惯容结构加入工作,进而提供所需的等效惯性力。
