摘　　要：为了减小和抑制分裂导线的舞动幅值,防止舞动灾害的发生,提出了一种对称式双质量弹簧减振结构的防舞器.本文阐述了防舞器基本结构和防舞原理,通过对基本参数进行设计,基于ABAQUS软件进行有限元建模,将该防舞器与摆杆-质量-弹簧防舞器和传统双摆防舞器进行模拟对比,分析其抑舞效果,并优化布置方案.结果表明:该防舞器结构简单、易于安装、适用于任意分裂数导线且防舞性能良好;可弥补摆杆-质量-弹簧防舞器对扭转振动抑制的不足;防舞器的防舞效果稳定,对垂直和扭转方向抑舞效果均优于双摆防舞器,虽然风速增大会导致防舞性能降低,但抑舞效果仍能高达75%以上;同时对防舞器布置方案进行改进能有效提升防舞效果并节约成本.In order to reduce and suppress the galloping amplitude of the bundled conductor and prevent the occurrence of galloping disasters,an anti-galloping device with symmetrical dual-mass spring damping structure is proposed.The basic structure and anti-galloping principle of the anti-galloping device are expounded,and the finite element modeling is carried out based on ABAQUS software by designing the basic parameters,and the anti-galloping device is simulated and compared with the pendulum-mass-spring anti-galloping device and the traditional double pendulum dampers,and the galloping suppression effect is analyzed,and the arrangement scheme is optimized.The results show that the anti-galloping device is simple in structure,easy to install,suitable for any bundled conductors and has good anti-galloping performance.It can make up for the deficiency of the pendulum-mass-spring galloping inhibitor on torsional vibration;The anti-galloping effect of the anti-galloping device is stable,and the galloping suppression effect on vertical and torsional directions is better than that of the double pendulum dampers,although the increase of wind speed will lead to a decrease in the anti-galloping performance,but the galloping suppression effect can still be as high as 75%;At the same time,the arrangement scheme of the anti-galloping device can be improved to effectively improve the anti-galloping effect and save costs.
