analysis can be provided as part of the
verification calculations.
Later on, the vehicle acceptance and
qualification tests are supported by vehicle
dynamics calculations. During the test, the
predicted and measured vehicle
performance can be compared and the
modelling improved to gain experience for
future projects.
Although the engineering process has
been completed when the vehicle is
introduced into service, issues may
subsequently, in rare situations, arise
which then may require assessment using
further vehicle dynamics simulations.
