Piezoelectric tuned mass rate independent damper and parameter design method thereof
The invention discloses a piezoelectric tuned mass rate-independent damper and a parameter design method thereof, compared with a traditional tuned mass damper, an original linear viscous damping element in the damper is replaced and changed into a rate-independent linear damping element, so that damping force independent of vibration frequency is provided. Furthermore, after the damping element is replaced, in order to enable the displacement response control effect of the piezoelectric tuned mass rate independent damper on the structure under the excitation of the seismic load to be optimal, on the basis of a main structure and a ground motion displacement transfer function, the minimum value of the displacement peak response of the main structure is taken as a target, and the displacement response control effect of the piezoelectric tuned mass rate independent damper on the structure under the excitation of the seismic load is optimized. The invention provides a parameter optimization design method of the piezoelectric tuned mass rate independent damper.
本发明公开了一种压电式调谐质量率无关阻尼器及其参数设计方法，相比传统的调谐质量阻尼器，对阻尼器中原有的线性粘滞阻尼元件进行了替换，将其改变为率无关线性阻尼元件，从而提供独立于振动频率的阻尼力。并且进一步地，在进行了阻尼元件的替换后，为了使压电式调谐质量率无关阻尼器对结构在地震荷载激励下的位移响应控制效果达到最优，本发明基于主结构和地面运动位移传递函数，以主结构位移峰值响应取最小值为目标，提出了压电式调谐质量率无关阻尼器的参数优化设计方法。
