Abstract EN
Structures which are commonly used in our infrastructures are becoming lighter with progress in material science.
These structures due to their light weight and low stiffness have shown potential problem of wind-induced vibrations, a direct outcome of which is fatigue failure.
In particular, if the structure is long and flexible, failure by fatigue will be inevitable if not designed properly.
The main objective of this paper is to perform theoretical analysis for a novel free pendulum device as a passive vibration absorber.
In this paper, the beam-tip mass-free pendulum structure is treated as a flexible multibody dynamic system and the ANCF formulation is used to demonstrate the coupled nonlinear dynamics of a large deflection of a beam with an appendage consisting of a mass-ball system.
It is also aimed at showing the complete energy transfer between two modes occurring when the beam frequency is twice the ball frequency, which is known as autoparametric vibration absorption.
Results are discussed and compared with findings of MSC ADAMS.
This novel free pendulum device is practical and feasible passive vibration absorber in the mitigation of large amplitude wind-induced vibrations in traffic signal structures.
