Composite bidirectional self-adaptive liquid damper
According to the combined type bidirectional self-adaptive liquid damper, a rectangular tuning liquid damper and a U-shaped tuning liquid column damper are connected through an electromagnetic valve, and the length of the center line of water in the U-shaped tuning liquid column damper can be adjusted in real time so as to retune the natural vibration frequency; a telescopic rod in the driving system can operate a steel partition plate to separate a rectangular tuned liquid damper to achieve preliminary adjustment of frequency, and then accurate adjustment is achieved through opening and closing of an electromagnetic valve. The outer surface of the electric gate is coated with the high-damping rubber coating, an electric rotating shaft in the driving system can drive the electric gate to rotate, the electric gate is closed, and the contact area of liquid in the U-shaped tuning liquid column damper and the high-damping rubber coating is changed to change the frequency and the damping ratio of the electric gate, so that a better vibration control effect is achieved. Bidirectional vibration of the structure in a plane can be controlled at the same time, and the safety and comfort of the structure are improved.
本发明提供了一种复合式双向自适应液体阻尼器，矩形调谐液体阻尼器和U型调谐液柱阻尼器通过电磁阀门实现连接，可实时调节U型调谐液柱阻尼器中水中心线的长度以重调谐自振频率；驱动系统内的可伸缩杆可操作钢隔板分隔矩形调谐液体阻尼器实现频率的初步调节，再利用电磁阀门的开关实现精确调节；高阻尼橡胶涂层涂于电动闸门的外表面，驱动系统内的电动转轴可带动电动闸门旋转，关闭电动闸门和改变U型调谐液柱阻尼器内液体与高阻尼橡胶涂层的接触面积以分别改变其频率和阻尼比，以取得更佳的振动控制作用。本发明可同时控制结构在平面内的双向振动，提高其安全性和舒适性。
