Abstract

Developments in vehicle
technology reveal that increased demands on vehicle comfort and fuel efficiency
in the vehicles require to design more efficient powertrain systems. Vibrations
originated in the engine need to be well optimized and controlled at desired
limits. For this purpose, modal analyis for vehicle components is the main
analysis method to evaluate the vibration behaviours. During vehicle design,
important parameters for vehicle vibration such as inertia and stiffness are
investigated and modified values to be replaced to get lower vibration values
by means of the modal analysis. In this study, the truck powertrain system is
modelled with real system values by the 1-D analysis software program and modal
analysis is performed to find mode shapes and vibration magnitudes of the
powertrain system components. Mode shapes of the clutch damper was investigated
by changing damper stiffness values and the other components variables were
taken constant to evaluate the stiffness effects on the system by modal
analysis.
