Inerter hysteresis damping type auxiliary cable
The invention belongs to the technical field of engineering structure vibration control, and particularly relates to an inerter hysteresis damping type auxiliary cable which comprises an inerter hysteresis damping device, an auxiliary cable body and a connecting cable clamp assembly. The inerter hysteresis damping device is composed of an outer frame, a rubber damping element, an inner box, a ball screw, a rotating mass block and a connecting clamping piece. The auxiliary cable adopts a steel strand; the inerter hysteresis damping device is connected with the cable clamp through the rotating shaft and finally connected to the inhaul cable. According to the inerter hysteretic damping type auxiliary cable, the inerter hysteretic damping device adopts the form that the shearing type high-damping rubber damper is connected with the inerter in parallel. The high-damping rubber damper has the advantages of being large in rigidity, free of liquid substances and the like, and therefore the high-damping rubber damper can be combined with the auxiliary cable very easily. The inerter can achieve the displacement amplification effect, and additional damping provided by the damper can be effectively improved. The inertia hysteresis damping type auxiliary cable vibration reduction measure provided by the invention is expected to better realize the control on the wide-frequency-domain multi-mode vibration of the ultra-long stay cable.
本发明属于工程结构振动控制技术领域，具体涉及一种惯容滞回阻尼型辅助索，包括惯容滞回阻尼装置、辅助索及连接索夹组件。惯容滞回阻尼装置由外框、橡胶阻尼元件、内盒、滚珠丝杆、旋转质量块及连接夹片组成；辅助索采用钢绞线；惯容滞回阻尼装置通过旋转轴与索夹连接，最终连接于拉索。本发明所述的惯容滞回阻尼型辅助索，其惯容滞回阻尼装置采用剪切型高阻尼橡胶阻尼器并联惯容器的形式。其中，高阻尼橡胶阻尼器具有刚度大、无液体物质等特点，因此，其极易与辅助索结合。惯容器可起到位移放大的效果，能够有效提升阻尼器所能提供的附加阻尼。本发明提出的惯容滞回阻尼型辅助索减振措施，有望更好实现对超长斜拉索宽频域多模态振动的控制。
