SET-UP Kart Simulator - Kart Full Simulator for optimal technical development and to find the best kart setup

Presentation

The experience that you accumulate on track is very important, but often there isn't the possibility to try all the technical choices that you'd like, or there isn't the time to find the best setup on a specific track, or with specific conditions.

Therefore to have a disposition a simulation software is fundmental to multiply your experience and to test fastly the different solutions finding the best, before and better of your competitors.

NT-Project has developed in these years this software creating calculation models between the most sophisticated in the whole racing sector, at the purpose to analyze with the maximum precision every aspect that affects the kart performance.

How it works?

In the software you must enter the technical features of the kart, and the choices of setup that you want testing, and the software simulates the best performance that is possible to obtain with that configuration, and the behaviour of driving of the kart.

The software SET-UP Kart Simulator takes account of all the features that affect the performance and the behaviour of the kart, anyway as we'll see later are all data findables easily, with simple measurements, or easy experimental tests.

KART AERODYNAMICS

The aerodynamics drag is one aspect that affects the performance, for this has been obtained and studied the values more usuales for the kart of the different categories. These data are already inserted in the software.

CHASSIS GEOMETRY

The main dimensions of the chassis, the angles of the C (kingpin and caster) are fundmentals for the distibutions of the loads on the wheels in the different driving conditions. These data are presents in the homologation fiche of the chassis, or are easily measurables.

CHASSIS FEATURES

The material used and the dimensions, of the chassis tubes, and of the spindle, are fundmental for the flexural behaviour of the chassis, and therefore to evaluate the camber angle that the tyres have in all the driving conditions, acceleration, braking, and corner. These data are in the homologation fiche, and are easily measurables, furthermore are integrated with the elasticity informations already detected and inserted in the software.

The torsional stiffness is probably the feature that more affects the behaviour of the chassis, and therefore the choices of setup that you must perform, because determines the chassis roll and the lifting of the rear wheel on corner. Thanks at one of our free utility is sufficient to have two or four scales to find easily this important data.

KART BALANCE

The balance of the kart and gravity height, are the main factor that affect the dynamic behaviour of the kart , therefore to know these data is very important. Thanks at one of our free utility is sufficient to have two or four scales to find easily these important data

TYRE FEATURES

In the competitions today the tyre is key aspect, because if you don't succeed to explot at the best the tires, all the work on the engine, on the chassis, and of the driver, come nullified.
For this reason great part of the work performed for this software has been studied deeply the features of the kart tyres. The main data are all presents in the homologation fiche of the tyres.

TYRE PLY FEATURES

Together at the dimensions and at the general features of the tyres, is of fundmental importance for the tyre behaviour to know the features of the carcass ply, for this in our little laboratory, optimally managed from Bruno, and thanks to the help of the friends Salvatore and Stefano, we've made technical tests fundmentals to complete the knowledge of the tyres, in addition at the informations indicated in the homologation fiche. In fact we've determined the ply stiffness of all the main kart tyres, evaluating also as the stiffness change in function of the temperature, to see how happen to the tyre slip in the real operating conditions.

ENGINE POWER and GEARBOX RATIO

The power provided from the engine obviously is one of the aspects more influentials the performance of the kart. Same speech for engine with gearbox about the ratio of the different shift gears. In the software you must therefore enter the power curve of the engine detected at the dyno, and the number of teeth of the gears for each ratio, that are indicated in the homologation fiche of the engine.

If you don't have the possibilty to test the engine at dyno, in the software SET-UP Kart Simulator there is a functionality that allows to calculate with precision the power curve of the engine exploiting the data acquired from your acquisition system in a session on track.

TRACK LINE

The track line chooses from the driver affects significantly the lap time, for this in the software SET-UP Kart Simulator together to be inserted the lines used on the main tracks and categories of Italy and of the world, is possibile to use the data acquired from your acquisition system to calculate the track line, and therefore to perform the simulations of set-up to exploit at the maximum the driving of your driver.

KART SET-UP

After the data fixed for chassis, engine, tyres, and track, you must enter the choices of setup that you want testing. The software to compare three configurations of kart setup, so will be easy to make a comparison of the performance and of the behaviour of the kart. The software allows to compare the choices for:

final drive ratio

engine speeds operation range

braking distribution

chassis setup (kart widths, caster, toe, and camber)

rear axle features

tyres pressure

Results

After that you've entered the technical data of the kart, and the choices of setup that you want testing, the software SET-UP Kart Simulator in a few seconds calculates the lap time, and the conditions of oversteer and understeer that the driver must manage in function of the setup used.

Lap Time	Oversteer-Understeer Kart

The lateral slip of the kart that the driver must manage with the driving comes analyzed in the detail, in fact the software calculates the slip angle, both at the front, both at the rear.

The calculation of the oversteer and understeer conditions that the driver must manage is fundmental because the simulator uses a virtual driver that succeeds to exploit at the best every setup, instead the real driver succeeds to go at the maximum only with the optimal driving feeling.

Apart the lap time, you can find the set-up that allows to have the best facility of driving, helping, above all the young driver, to find the optimal feeling, and therefore to race at the best.

Below we show an example of use of the software SET-UP Kart Simulator to find the best setup. In this example evaluate the effects of some modifications on the chassis setup.

After that you've entered the changes of setup that you want test, in a few seconds the software SET-UP Kart Simulator calculates the lap time for the two configurations, and the behaviour of oversteer and understeer of the kart.

Lap Time	Oversteer-Understeer Kart

In this example the new configuration (blue) allows to improve the lap time, and to reduce averagely the understeer of the kart. Thanks to the software SET-UP Kart Simulator you can therefore to check again before to go on track if the modifications that you think to make on the setup, gone on the right direction. This will give you great advantages above all in the race w.e where the time that you've is few, and you need to be immediately fast.

Moreover if the software shows an improvement on the lap time, or on the driving feeling, in the reality this will be again greater, because the virtual driver succeeds to fill the defects of the setup more than the real driver.

	Together to the global results, the effects of the setup modifications can be analyzed in the details, watching for each sector of the track where there avantages, or disadvantages, for speed, or lateral slip.

This example shows how thanks to the software SET-UP Kart Simulator is easy to analyze the choices technical, and of set-up, that you can try, finding quickly and with precision the solutions that allow to improve the performance and the driver feeling for his driving style.

In the development phase the software SET-UP Kart Simulator allows to find:

chassis geometry

chassis torsional stiffness

kart balance

engine power curve

gearbox ratios

that in the different tracks and conditions allow to obtain the best perfromance.

Instead in the phase of setup on track the software SET-UP Kart Simulator allows to find:

final drive ratio

braking distribution

chassis front and rear width

camber, caster and toe

axle hardness

tyres pressure

that foe each condition and for each driving style provide the best performance and the best feeling.
