Summary: | Engine mounting system is an essential
component to a vehicle in providing the isolation of vibration
and noise which are generated by the engine. While various
system designs have been studied for improvements, less
attention were given to study the effects of vibrational load to
subcomponents of the mounting system – for example: the
engine bracket. At high frequency working condition, the
engine bracket may experience fatigue failure due to
cumulative vibrational loading. Henceforth, any efforts to
further reduce the structural weight of the said brackets may
degrade its strength and this may lead to catastrophic result.
This study aimed to enhance the mechanical property of an
engine-mounting bracket with respect to cyclic load by means
of weight-reduction topology optimization. An actual enginemounting bracket under vibrational load transmitted was
modeled and analyzed using two different computer aided
design software. An improved design of engine mounting
bracket was modeled by reducing its total weight via the use
of HyperWorks. In conclusion, this study has discovered an
incremental of stress concentration area across the bracket
when predetermined load is applied to the weight-reduced
engine bracket |
