X. CONCLUSIONS
As the aim of the project is to reduce the damping
effects of the driven shaft, the major sources used for this
purpose are composite materials. By using three different
kind of composite materials steel, carbon epoxy, E-glass
epoxy the project has been carried out. For controlling the
damping effects by using passive damping the materials
which reduces these damping like rubber are employed in
the center of the shaft. Shaft is analyzed using layer
stacking method in ANSYS software which utilizes finite
element method technologies. These layer stacking
techniques are employed for shafts with and without
damping material. Static analysis is done for observing the
steady loading conditions. The results have shown that the
shaft with damping material made of any composite
material has less damping effects when compared with
shaft without damping material. The results have clearly
proved that the static deflection of the shaft made with
three composite materials with damping material when
compared with without damping material. For the purpose
of dynamic loading conditions and for determining natural
frequencies, mode shapes modal analysis is also done.
