Topic: INVESTIGATION OF COCONUT FIBRE BENEFICIATION FOR BIFURCATION AND CHAOS CONTROL IN DYNAMICAL SYSTEMS.
Description:
Bifurcation
is the study of changes in the topological structure of a system. A bifurcation
occurs when a small smooth change made to the parameter values of a system
causes a sudden qualitative or topological change in its behavior. Bifurcation
occurs in both continues and discrete systems such as structures and vibrating
machinery.
The
level of vibration in a structure can be attenuated by reducing either the
excitation, or the response of the structure to that excitation or both. It is
sometimes possible, at the design stage, to reduce the exciting force or motion
by changing the equipment responsible, by relocating it within the structure or
by isolating it from the structure so that the generated vibration is not
transmitted to the supports. The structural response can be altered by changing
the mass or stiffness of the structure, by moving the source of excitation to
another location, or by increasing the damping in the structure. Naturally,
careful analysis is necessary to predict all the effects of any such changes,
whether at the design stage or as a modification to an existing structure.
It is necessary to analyse the vibration of structures in order to predict the natural frequencies and the response to the expected excitation. The natural frequencies of the structure must be found because if the structure is excited at one of these frequencies resonance occurs, with resulting high vibration amplitudes, dynamic stresses and noise levels. Accordingly resonance should be avoided and the structure designed so that it is not encountered during normal conditions; this often means that the structure need only be analysed over the expected frequency range of excitation.
The
problems associated with structure and machinery vibration cannot be over
emphasized. The catastrophic behaviors of machinery in manufacturing industry
has led to the destruction of lives and properties over the years. The research
tends to evaluate the characteristics of machine and structure behavior to
vibrational sources and develop a new vibration damping attenuating material
using the coconut fiber for purpose of building an effective damping device for
dynamical systems.
