Assembly type damping device for wind power tower drum
The invention aims to disclose an assembly type damping device for a wind power tower drum. The assembly type damping device comprises a rigidity system, a mass system, a damping system and a protection system. The mass system is arranged on the lower part of the rigidity system, the damping system is arranged at the bottom of the mass system, and the protection system is arranged on the side surface of the damping system; the mass system is directly suspended on a hoisting assembly, initial starting force is not needed in a working state, the mass system can respond in time during tiny vibration, and sensitivity is good; the rigidity and the frequency of a product are continuously adjusted by adjusting the pendulum length, and the frequency is continuously adjusted; the size of a mass block is not changed when the frequency is adjusted, and the damping effect is guaranteed; friction and collision are carried out between particle swarms in the particle mass block and the interior of the shell, between the partition plates and between the particle swarms, a large amount of vibration energy is consumed, and structural response caused by external excitation is effectively reduced; and each part can be split into a plurality of assembly type parts, so that transportation and field installation are facilitated.
本发明的目的在于公开一种用于风电塔筒的装配式阻尼装置，包括刚度系统、质量系统、阻尼系统及防护系统，质量系统设置在刚度系统的下部，质量系统的底部连接有阻尼系统，阻尼系统的侧面设置有防护系统；质量系统直接悬挂在吊装组件上，在工作状态无需初始启动力，在微小振动时可以及时反应，灵敏度良好；通过调节摆长来连续调节产品刚度和频率，实现频率的连续性调节；调节频率时不改变质量块大小，保证了减振效果；颗粒质量块内部的颗粒群与外壳内部、隔板之间以及颗粒群之间进行摩擦、碰撞，大量消耗振动能量，有效减小外界激励引起的结构响应；各个部分均可拆分为若干个装配式构件，便于运输及现场安装。
