摘要

本文考虑了类建筑结构在悬臂梁结构中与柔性减振器耦合时的动力响应的理论和实验分析，同时考虑了与其质量相关的重力效应。采用欧拉-拉格朗日公式，将FVA视为一个广义的一自由度系统，得到了完整系统的数学模型。通过对非线性运动方程进行线性化，可以获得以FVA长度作为设计参数的调谐条件。最后给出了一些实验结果来验证和说明整个系统的动态性能。

Application of a Flexible Vibration Absorber for Passive Vibration Control in a Civil Structure

This paper considers the theoretical and experimental analysis in the dynamic response of a building-like structure when it is coupled to a Flexible Vibration Absorber (FVA) in cantilever beam configuration taking into account the gravitational effects associated with its mass. The mathematical model of the complete system is obtained using the Euler-Lagrange formulation considering the FVA as a generalized system of one degree of freedom. By carrying out a linearization of the nonlinear equations of motion, it is possible to obtain the tuning condition using the length of the FVA as a design parameter. Finally, some experimental results are included to validate and illustrate the dynamic performance of the overall system.
