| dc.description.abstract | Since racing vehicle has greater risk of injury
and vehicle damage than any others urban vehicle, this paper
presents the design, modeling and performance study of crash
damper in a racing electric vehicle. Using lumped parameter
model (LPM) as analytical approach, the development model of
hydraulic crash damper is used to absorb or to dissipate the
kinetic energy on frontal crash. The mathematical model
between initial model and development model is derived to
obtain responses of both vehicle and occupant. Plot 3D surface
from numerical simulation is used to obtain optimum value of
development model. The results in time response are also plotted
to compare both initial model and development model.
Development model also claimed that can reduce in vehicle
deceleration, occupant deceleration and vehicle deformation in
the range of 25% to 28.1% than initial model. | en_US |
