Abstract

Clutch components rotating
at high speed remain under the influence of high centrifugal forces. Therefore
at the high rotational speeds flywheel is subjected to extreme forces that may
cause severe cracks and breakages. Burst test validates the mechanical robustness
of the flywheel under various rotational speeds. In this study comparative
analysis have been performed experimentally and numerically in order to confirm
correlation of the results. Centrifugal endurance test called burst have been
performed in addition to finite element analysis which has been used for
calculating stress values of flywheel. Additionally design of experiment method
has been used for obtaining the response surface that approximates the stress
behavior of automobile flywheel. This provides strong correlation between FEA
results and data fittings calculation that gives extra contribution to reduce
the design process.  This study gives
ideas for the stress improvement of flywheel by making experimental and
numerical comparison. Experimental and numerical correlations results taken
from this study can be used on the estimation of design robustness instead of
prototypes production which causes time and money consumption during flywheel
design and production process.
