Vehicle Ride Investigation Of Myvi With Adams Car

The objective of this project is to investigate the vehicle ride and handling of the Myvi using
the ADAMS Car simulation software and from the result obtained, studies will be carried on to
develop some effective improvements to optimize comfort and handling of Myvi. The Perodua
Myvi is one of the leading local cars in its class. However, it has its own share of problems when
it comes to ride and handling as they had been many complains circulating around saying that the
Myvi is not so comfortable both for the passengers and the drivers. Complains stated that even
small flaws on the road can cause a sufficient discomfort to the drivers and passengers. The
scope of study of this project will be as follow:
· Study about the vehicle ride and handling. This includes the factors that can affect the
ride and handling of a vehicle, the basic vehicle ride modeling and the handling modeling.
· Study and construct the model and simulate it in the ADAMS Car software to produce
the ride and handling results of the Myvi under different driving condition.
· Analyze the obtained results and propose some potential improvements that can be
implemented to optimize ride and handling of the Myvi.
The methodology for this project basically has more emphasis on using the ADAMS Car
software whereby the significant hardpoints are measured and inserted into the ADAMS Car
modeling software to model out the original Myvi suspension system. The suspension system
will then be modified in order to obtain the best feasible results. The findings that so far had been
obtained are the type of suspension the Myvi is using, which is the Macpherson for the front and
torsion beam at the rear. In addition, the rough calculation of the suspension ratio and the bump
to scrub ratio had been calculated as well but the value might change later in the project due to
some inconsistency in the measurements of the hardpoints obtained. The measurements of the
hardpoints for modeling had been attempted but the result was not accurate due to some
difficulty in the measuring process. Obtaining the hardpoints from Perodua itself will be the best
solution. The current progress is on hold while waiting for the reply from Perodua and trying to
figure out the new method of measuring the hardpoints in a more accurate way.
