摘要:
为了研究多重调频质量阻尼器(MTMD)振动控制体系用于空间结构时的减震性能,基于MTMD减震设计方法设计减震装置,并开展K6型单层球面网壳MTMD振动控制振动台试验.通过对比安装MTMD前后结构的位移响应,研究减震器自振频率、地震动波形以及地震动PGA等因素对MTMD振动控制效果的影响.试验结果表明,MTMD的振动控制效率均达到30%以上,且可降低位移值较大区间的振动持时;当减震器自振频率或地震动卓越频率与试验模型频率接近时,MTMD的振动控制效果更显著;当相同波形地震动PGA增加时,MTMD的振动控制效果降低.数值分析结果表明,理论计算值与实测值结果吻合较好,并可反映模型MTMD装置的振动控制效果趋势.
Abstract:
To study the shock-absorption performance of the multiple tuned mass damper(MTMD)vibration control system on spatial structures, a shock-absorption device was designed based on the MTMD shock-absorption design method, and MTMD vibration control shaking table tests were conducted on a K6 single-layer spherical reticulated shell. By comparing the displacement responses of the structure with and without the MTMD equipment, the effects of the shock-absorption’s natural frequency, ground motion wave and peak ground acceleration(PGA)of ground motions on the MTMD vibration control efficiency were investigated. The experimental results show that the vibration control efficiency of MTMD is more than 30%, meanwhile, the MTMD system can reduce the duration of the larger displacement response. When the natural frequency of the shock-absorption or the excellent frequency of the ground motion approaches the structural frequency, the vibration control efficiency of the MTMD increases. However, the increase of the ground motion PGA can reduce the vibration control efficiency of the MTMD. Furthermore, the numerical results agree with the experimental results and they can reflect the tendency of MTMD vibration control efficiency.
