Magnetorheological elastomer collision tuned mass damper
The invention discloses a magnetorheological elastomer collision tuned mass damper, and belongs to the field of civil engineering structure vibration control. The technical defect that an existing collision tuned mass damper cannot select proper collision rigidity according to real-time dynamic characteristics of a mass block to achieve maximum energy consumption is overcome, and the characteristics that the magnetorheological elastomer can generate collision deformation under the stress effect parallel to the magnetic field direction and the collision deformation range is wide are utilized; according to the maximum collision energy consumption required by the mass block, the optimal collision rigidity and collision damping of the magnetorheological elastomer are obtained in real time by changing the magnitude and direction of the current, and the maximum collision energy consumption is achieved.
本发明公开了一种磁流变弹性体碰撞调谐质量阻尼器，属于土木工程结构振动控制领域。本发明解决了现有碰撞调谐质量阻尼器无法根据质量块实时动力特性选择适合的碰撞刚度以达到耗能最大化的技术不足，利用磁流变弹性体在与磁场方向平行的受力作用下可发生碰撞变形且碰撞变形范围宽的特性，根据质量块所需的最大碰撞耗能，通过改变电流的大小和方向实时获得磁流变弹性体的最优碰撞刚度和碰撞阻尼，实现碰撞耗能的最大化。
