Mass damper of double-ball-screw system
The invention belongs to the field of dampers, and particularly relates to a mass damper of a double-ball-screw system. A ball screw inerter structure a, wherein the ball screw inerter structure a is mounted on the shock insulation layer; a ball screw inerter structure b, wherein the ball screw inerter structure b is mounted on the shock insulation layer; the sleeve combination structure is mounted on the shock insulation layer; and at least three roller limiters. When the external excitation effect is small, the equivalent inertia force generated by the device is provided through the work of the ball screw inerter structure a to ensure that the structure does not generate additional vibration, and when the external excitation effect is large, the equivalent inertia force generated by the device is provided through the work of the ball screw inerter structure b to ensure that the structure does not generate additional vibration. It is ensured that large enough equivalent inertia force is generated to play a response control role, and the purposes of small earthquake flexibility and large earthquake amplification are achieved.
本发明属于阻尼器领域，具体涉及一种双滚珠丝杠系统的质量阻尼器，包括隔震层；滚珠丝杠惯容结构a，所述滚珠丝杠惯容结构a安装在所述隔震层上；滚珠丝杠惯容结构b，所述滚珠丝杠惯容结构b安装在所述隔震层上；套筒组合结构，所述套筒组合结构安装在所述隔震层上；至少三个滚轮限位器。当外部激励作用较小时，本装置产生的等效惯性力通过滚珠丝杠惯容结构a工作来提供，确保结构不会发生附加震动，当外部激励较大时，本装置产生的等效惯性力通过滚珠丝杠惯容结构b工作来提供，确保产生足够大的等效惯性力以发挥响应控制作用，实现小震灵活，大震放大的目标。
