RaceSim  V 2.7.x  

.....is a vehicle dynamic analysis tool for:RaceSim Logo
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 RaceSim to customers needs and budgets (see Options paragraph).

Features

TOP

Tyre data input windowThe user friendly input and comprehensive helpfile of RaceSim makes the definition of the vehicle very easy, to reduce effort and increase 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.

RaceSim can be developed to a customers specific requirements. Contact D.A.T.A.S. Ltd. for further information

Summary

TOP

RaceSim is a full Windows based and compatible program. After many years of development and validation at the highest levels of international motorsport, RaceSim is now available in version 2.7.x.

RaceSim 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, RaceSim describes the behaviour of the complete vehicle very accurately and comprehensively. Many tools support the engineer while working with RaceSim. With a minimum of effort he gets a maximum of useful information.
 

By using RaceSim, 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.
