Eddy current tuned mass damper for draught fan tower vibration reduction and mounting method thereof
The invention relates to the technical field of vibration reduction, in particular to an eddy current tuned mass damper for draught fan tower vibration reduction and a mounting method thereof. The eddy current tuned mass damper comprises an eddy current damping generator, a swing assembly, and a limiting assembly; the eddy current damping generator comprises conductor plates and magnetic steel which are arranged at intervals; the swing assembly comprises a swing rod and a mass block; the mass block is fixedly connected with the lower end of the swing rod; the magnetic steel is fixed to the lower end of the mass block; the limiting assembly comprises a limiting rope; the limiting rope is of an annular structure; the limiting rope is located on the periphery of the mass block; and the limiting rope is used for limiting displacement of the mass block. According to the eddy current tuned mass damper for draught fan tower vibration reduction and the mounting method thereof, the flexible limiting rope is arranged on the periphery of the mass block, and the mass block is limited to generate overlarge displacement, so that the mass block can be effectively prevented from colliding with thewall of a fan tower drum and an elevator, and potential safety hazards are eliminated; and the limiting rope is adopted for flexible limiting, the structure is simple, the buffering effect is obvious, the good limiting effect is achieved for collision at different angles, and the fatigue problem is not likely to happen.
本发明涉及减振技术领域，具体涉及一种用于风机塔筒减振的电涡流调谐质量阻尼器及其安装方法，电涡流调谐质量阻尼器包括电涡流阻尼产生器和摆动组件，电涡流阻尼产生器包括间隔设置的导体板和磁钢，摆动组件包括摆杆和质量块，质量块固定连接在摆杆的下端，且磁钢固定在质量块下端，还包括限位组件，限位组件包括限位绳，限位绳为环状结构，限位绳位于质量块的外围，限位绳用于限制质量块的位移。本发明通过在质量块外围设置柔性的限位绳，限制质量块产生过大位移，可以有效防止质量块碰撞风机塔筒筒壁、电梯，消除安全隐患；且采用限位绳进行柔性限位，结构简单，缓冲效果明显，对于不同角度的碰撞均有良好的限位效果，且不易产生疲劳问题。
