摘要
滚动型单面碰撞调谐质量阻尼器是一种由小球、圆形轨道、黏弹性材料挡板组成的减振装置,通过小球与挡板的碰撞耗能以及小球与圆形轨道间的摩擦进行减振。基于Lagrange变分原理,建立单自由度结构与滚动型单面碰撞调谐质量阻尼器的运动方程,研究不同质量比下滚动型单面碰撞调谐质量阻尼器的参数优化,分析自由振动、简谐激励以及地震作用下滚动型单面碰撞调谐质量阻尼器的减振性能。结果显示,滚动型单面碰撞调谐质量阻尼器具有良好的减振效果。
Single-side pounding tuned rotary mass damper(SS-PTRMD) is a vibration damping device composed of a small ball,a circular track,and a viscoelastic material baffle,which can reduce structural vibration by dissipating the energy of the collision between the small ball and the baffle and the friction between the small ball and the circular track.Based on the Lagrange variational principle,the kinematic equations of the single-DOF structure and the SS-PTRMD are established.The parameter optimization of the SS-PTRMD under different mass ratios is studied.The vibration damping performance of the SS-PTRMD under free vibration,harmonic excitation and earthquake is analyzed.The results show that the SS-PTRMD has a good vibration reduction effect.
