The tuning of a simplified current blocking shunt circuit able to mitigate the vibration amplitude of multiple structural resonances is addressed in this article. The proposed strategy exploits the two-port network formalism in combination with physically motivated approximations to tune sequentially the electrical elements of the different branches of the shunt circuit. The resulting tuning method does not resort to optimization algorithms and requires only the knowledge of quantities that are easy to measure experimentally. It is demonstrated both numerically and experimentally using a piezoelectric beam.

使用简化的电流阻断分流电路的多模态振动阻尼

本文讨论了对能够减轻多个结构共振的振幅的简化电流阻塞分流电路的调谐。所提出的策略利用双端口网络形式主义结合物理激励的近似来顺序调整分流电路不同分支的电气元件。由此产生的调整方法不诉诸优化算法，只需要易于通过实验测量的数量知识。它使用压电梁进行了数值和实验证明。
