Red Bull Technology post-rig shaker - RB4

I would appreciate any comments on the "Enstone" rig (last video). It appears to have been supplied by MTS, and combine "7-post" & "K&C" functionality. That seems to make some logical sense, but perhaps presents some potentially difficult compromises.

It's a combination of MTS- and Instron- equipment.

Exactly, anything can fail if it's overloaded. The goal is to find that limit, and it is validated by this kind of testing.

The front wing is a good example, a certain amount of flex is allowed, and no team would be foolish not to exploit this to the maximum. And since you don't want to construct a part too heavy, you want to build it to last just one predicted amount of time/or certain cycles of stress.

I just adore the 7 post rig, it's functions and how it's utilized. What's really cool is that during a race weekend, the data from the cars on track is fed back to the factory, and that data is used with the rig to refine the setup for the car. Drive the car in practice, feed the data back to the factory, the technicians and engineers work all night on setups, feeed the new data back to the team, and in the morning, the team has all kinds of fresh data they can input into the car to enhance performance.

You have to explain this one!

In the very short video I cant see any K&C feature working on. Can they use them while the postrig simulation is on?

Whats the tape on the tyres?

I don't think the two types of test "mix" particularly well, although both require a seismic mounting block and a high quality measurement & recording system.

The clues are the multi-degree of freedom wheel position measurement devices shown at the start of the video, and the synergistic platforms (hexapods) supporting the front wheels. The latter can control position of the contact patch in all six freedoms. The main compromises are load measurement, I suspect, and the quality of the hexpod bearings.

Whats the tape on the tyres?

I would guess that is used to prevent the compound gluing itself to the platforms. Talcum powder on a smooth surface also works, as does a floating top plate.

I can't assist with anything technical but having watched the old Jordan 'do' the Monoco GP,(not sure who was the driver that weekend) in the factory shaker room -they would beam data back to assist settings then beam the results to the team- it really showed how much the car is thrown up and around during the lap and it was quite erie as it was dead silent except for the car moving around. Reminded me of Joseph Cooper on the dummy keyboard in face the music.. (bet not many remember that programme!)
