Abstract
This work presents a numerical-experimental study of vibration control for a system with one degree of freedom, formed by a base that slides on an air rail. An inverted pendulum tuned mass damper (IP-TMD) is designed to be installed on the top of the sliding base and, hence, to control the vibration thereof. Initially the natural frequency of the system with one degree of freedom is calculated, the initial parameters for the geometry of the IP-TMDare adopted according to an experimental model and, later, an optimization with a genetic algorithm is performed. A stability analysis of the system is made to obtain the minimum value for the rotational stiffness constant k, which connects the inverted pendulum to the sliding base. Analysis in time and frequency domain are performed for an harmonic load applied to the sliding base. Lagrange equationswere used to obtain the equations of motion for the system with one degree of freedom (sliding base) and for the controlled system with two degrees of freedom (sliding base with IP-TMD)
