Abstract
This work presents the results obtained by an experimental study of vibration control for a system with a single degree of freedom, composed by a sliding base on an air track. An inverted pendulum-type tuned mass damper (TMD-IP) is installed on the sliding base to reduce its displacements. First, a reduced model is built using a 3D printer. The experimental model consists of two parts: the mains system, which is the sliding base; and the inverted pendulum (TMD-IP). The model can be tested as a one-degree-of-freedom system using only the base or as a two-degree system of freedom system after connecting the TMD-IP to the sliding base. The CIDEPE air rail is used to provide the sliding base displacement, which will receive the TMD-IP. The acquisition of the response data in the time domain is done through the software CvMob, which performs image acquisition and was produced by the Nucleus of Technological Innovation in Rehabilitation - NITRE, Federal University of Bahia.
Highlights
There are several ways to avoid the effects of excessive vibration, among them passive structural control
For example by installing devices in which some of the energy that a dynamic load applies to the main structure is absorbed or transferred. An example of this type of control is inverted pendulum systems functioning as tuned mass dampers, TMDIP [1]
Anh et al [2] compared the efficiency of the control exerted by an inverted pendulum and a simple pendulum on an inverted pendulum-type main system and found the best performance for the TMD-IP
Summary
There are several ways to avoid the effects of excessive vibration, among them passive structural control. For example by installing devices in which some of the energy that a dynamic load applies to the main structure is absorbed or transferred. An example of this type of control is inverted pendulum systems functioning as tuned mass dampers, TMDIP [1]. Anh et al [2] compared the efficiency of the control exerted by an inverted pendulum and a simple pendulum on an inverted pendulum-type main system and found the best performance for the TMD-IP. Majcher&Wójcicki [3] analysed numerically, the influence of vertical oscillations caused by an earthquake in a tall building, and the efficiency of a simple pendulum type tuned mass damper (TMD), as a control system
