分析了安装在柔性桥梁主梁跨中的调质阻尼器（ＴＭＤ）对涡激共振的抑制阻尼效果．分析中采用了Ｓｃａｎｌａｎ提出的销定（Ｌｏｃｋ－ｉｎ）区域的半经验和半解析非线性气动力模型．此外还对ＴＭＤ对涡激共振的阻尼效果进行了参数优化分析，给出了ＴＭＤ参数最优计算公式．
The damping effect of vortex-induced resonance (TMD) on the TMD installed in the span of flexible bridge is analyzed. Semi-empirical and semi-analytical nonlinear aerodynamic models of the Scan-Lock-in region were used in the analysis. In addition, the optimization of the damping effect of vortex induced by TMD on TMD is also analyzed, and the optimal calculation formula of TMD parameters is given.
