Abstract:
The present article analyses a 7 degrees of freedom full car model of a light
four-wheel wheeler formulated analytically and using the bond graph/Simulink
technique. A full car model formulated using the Bond graph/Simulink technique
is fed with the bump, pothole, harmonic, and random excitations to analyze the
vehicle’s dynamic behavior. The bond graph/Simulink model is validated by
comparing its results with that of the analytical model when subjected to
circular bump inputs and comparing its results with that of the field test when
subjected to random inputs. The vehicle model is fitted with a skyhook control
strategy on the axles and the response of the semi-active system is compared
with the passive system. The present analysis suggests that a vehicle system
with semi-active suspension shows improved vibration isolation characteristics
as compared with passive suspension system when subjected to different types of
excitations.
