Project Title:
Optimal Passive Vibration Suppression using TMDs in
a First Order Laminated Composite Beam by Finite Element Method
Passive vibration suppression
has been used in many fields of industry such as Civil engineering, Aerospace
and Automotive engineering. One of the simplest passive techniques is using
the so-called tuned mass damper (or TMD) or a vibration absorber. A tuned
mass damper, consisting of a mass, damping, and a spring, is commonly
attached to a vibrating primary system for suppressing undesirable
vibrations. The natural frequency of the TMD is tuned in resonance with the
fundamental mode of the primary structure, so that a large amount of the
structural vibrating energy is transferred to the TMD and then dissipated by
the damping as the primary structure is subjected to external disturbances. In this project, the
finite element equation for a laminated composite beam carrying one or
multiple TMDs is derived and the behavior of the
beam is studied through this model. In the next step the parameters of the
TMD and the composite beam are optimized for the minimum displacement at
specified vibration modes of the system. |
