Active, semi-active and passive control intelligent exchange self-adaptive tuned mass damper
The invention provides a self-adaptive tuned mass damper capable of intelligently switching active, semi-active and passive control, which comprises a damper passive control part, a servo control part, an active control part, a semi-active control part and a health monitoring part, and is characterized in that the servo control part uniformly controls the active control part, the semi-active control part and the health monitoring part; the two-way vibration control of the structure is realized through smooth two-way sliding of the friction pendulum support in a plane; the jack is used for providing active control force for the friction pendulum support so as to ensure that the mass block can slide under tiny wind vibration to start working, and the overlarge stroke of the mass block under extreme disasters can be controlled; the relative movement between the damping steel plate and the damping liquid in the damping groove is used for providing bidirectional damping force; the accurate instantaneous vibration frequency of the damper is ensured through variable stiffness control, and the bidirectional vibration reduction effect of the damper is improved; the health monitoring part stores, transmits and analyzes real-time vibration signals in real time so as to ensure normal work and safety of the structure.
本发明提供了一种主动、半主动、被动控制智能调换的自适应调谐质量阻尼器，包括：阻尼器被动控制部分、伺服控制部分、主动控制部分、半主动控制部分及健康监测部分，伺服控制部分统一控制主动控制部分、半主动控制部分和健康监测部分；通过摩擦摆支座在平面内光滑双向滑动以实现结构的双向振动控制；用千斤顶为摩擦摆支座提供主动控制力，以确保质量块在微小风振下能够滑动以启动工作，并能控制其在极端灾害下过大的冲程；用阻尼钢板与阻尼槽中阻尼液间的相对运动提供双向的阻尼力；变刚度控制以确保阻尼器准确的瞬时振动频率，提高其双向减振效果；健康监测部分实时储存、传输及分析实时振动信号以确保结构的正常工作及安全性。
