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.
