The methods of weight transfering in Formula 1 cars

[mahesh248]

how do they transfer weigth ..? i am new to this forum...i have read some wonderfull topics and learnt a lot just reading it ..plz let me know abt the methods of weight transfering ...

I'm not sure what your question is pointing to, but I can tell you that moving masses while the car is being driven is disallowed. It would be considered an active system.

Apart from that, weight transfer occurs during some kind of accelleration of the car, it is a simply physical principle. Weight is transferred to the front of the car under braking, to the left when cornering to the right and so on...

Welcome to the forum!

cool i got the idea ..so stiffning the anit roll bar is a kind of weight transfer ..or what is it m confused ...?

"U dont want the chassis to roll so much!!!!!!"

anti roll bars or stabiliser bars are simple mechanical parts....from the word anti roll....u should understand that it restricts roll of the chassis.....let me give u an example......say u have springs or suspension on the car.....wht will hapen when the car takes a fast corner.....the chassis rolls.....this is evident when u take ur FORD on a track........but now take the same FORD without any suspension(assume) wht will happen???? there is no roll of chassis......

NOw since the above case cannot be done....because of the simple fact that it will be awfully bumpy even in a track.....u need to provide some sort suspension which is springs......now once u have appplied springs the chassis will roll...... now if u want to limt roll .....u aplly the anti roll bars........get it!!!!!

u need to remember this, once u restrict chassis roll u will increase wt transfer.....which is done by the anti roll bar.......

[cfditya]

wt transfer is not moving parts or weights physically in the chassis.....
Its fundamental engineering dynamics(physics)....which u cant feel.....i guess u get the picture!!!!!!!

There are two types of weight transfer Static and dynamic.

In the run up to the season we talk a lot about the cars shifting weight forward in the car to suit the tyres. This weight shift is a design consideration and only affects the car at a stand still.
This is altered by either moving ballast or altering the relative length of the car (i.e longer gearbox shifts weight forwards)

Then there is dynamic weight shift, this affects the car as is accelerates, brakes and corners. This is managed by the springs, dampers, antiroll bars and 3rd springs.

well i got it now ..i think my phrasing of the question is wrong ...So the well there is no actually weight transfer when the anit roll bar is stiffined ... only when the body is in motion it effects ......Thanks Green snake ...

Here's an article about weight transfer as it applies to all cars, not just F1 racing cars. The topic can get quite involved, but this should get you started.

All answers to your questions Mahesh are correct, but there is another kind of weight transfer in any car, and especially in racing cars, and constructors doing a great job preventing that. Moving of liquids and driver itself during cornering, breaking and accelerating is a big problem if you want to improve your time every hundreds of the second. All tanks with liquids have built in separators to prevent movements of liquids and improve stability of the car. Even movement of driver head in corners is a problem (not so big, but still a problem) because is very high considering car center of gravity.
