V 2.7.x |
|
.....is a vehicle dynamic analysis tool for:
The designer during the concept of a new project to compare different
vehicle layouts in the simulation before any detailed design takes place.
For example the mass and power output of the engine can be modified very
easily, to determine the effect of CG, inertias and power on car performance
at different tracks.
And
the race engineer to run different setups and optimize the vehicle for the
next session/race... The wind has changed from yesterday, the gear ratios
and wing settings should be optimized... Or the driver has a problem riding
over a kerb and the engineer wants to try different spring / bump stop /
damper combinations.
.....is available in two levels. To fit
to customers needs and budgets (see
Options paragraph).

efficiency. Many extra tools support the engineer in his work.
The vehicle model is divided into manageable sub-groups (e.g.
engine, gearbox, suspension, tires...). Every group has its own data file,
where the parameters are stored.
The very comprehensive vehicle model covers nearly all
possible setup/design changes.
can be developed to a customers specific requirements.

the Dallara F3 Version
is a full Windows based and compatible program. After many years of
development and validation at the highest levels of international motorsport,
is now available in version 2.7.x.
is currently used by championship and race winning teams in Formula One,
INDY, GP2, WS3.5, NASCAR, WEC/GT, F3, DTM, WRC (tarmac) and Super Touring.
With more than 1600 input parameters, over 480 dynamic calculated
output variables and a 15 degree of freedom dynamic model,
describes the behaviour of the complete vehicle very accurately and
comprehensively. Many tools support the engineer while working with
.
With a minimum of effort he gets a maximum of useful information.
By using
,
the engineer will get a much better understanding of 'his' car. The
selection of on track setup changes to the car will be much more effective,
because they are already preselected by the simulation. This becomes even
more important, as track time becomes more limited.
