The invention relates to the technical field of structural engineering, in particular to a built-in negative stiffness damping system for controlling internal and external vibration of an inhaul cable plane, which is used for controlling vibration of an inhaul cable main body and comprises a stand column, a cross beam, a negative stiffness device, a damper and a connecting rod, the cross beam is arranged above the stand column, and a first hole is formed in the top end far away from the stand column; the dampers are arranged on the side, away from the stand column, of the cross beam and connected with the inhaul cable body, and the dampers are symmetrically arranged along the vertical plane where the inhaul cable body is located. And the negative stiffness device is arranged in the hollow cross beam and is connected with the inhaul cable main body through the connecting rod. According to the built-in negative stiffness damping system for controlling the in-plane and out-plane vibration of the inhaul cable, when the inhaul cable vibrates in the in-plane and out-plane directions, the negative stiffness and damping effects are provided.
本发明涉及结构工程技术领域，尤其是涉及一种拉索面内外振动控制的内置负刚度阻尼系统，用于控制拉索主体的振动，包括立柱、横梁、负刚度装置、阻尼器和连接杆，所述横梁设置于立柱上方，远离立柱的顶端设置有第一孔洞，所述阻尼器设置于横梁远离立柱的一侧，并与拉索主体相连接，所述阻尼器沿拉索主体所在竖直平面对称设置；所述负刚度装置设置于内部中空的横梁内部，并通过连接杆与拉索主体相连接。本发明的一种拉索面内外振动控制的内置负刚度阻尼系统，在拉索发生面内面外两方向振动时，均提供负刚度和阻尼效果。
