seven-post shaker rig

[boardtrack]

Could you please share form, benefits & cost of 'seven-post shaker rig' time for an ICS team.

Thanks

It does a lot of things. But probably the most valuable is that the shaker rig can be programmed with actual data from any race track, and then can simulate that track condition at just about any speed and temperature while car is mounted on it. It will help develop suspension pieces, shock packages, etc. etc.

Think of it as the ability to test at any and all tracks without driver variations, whether the rules allow you to test there or not, any time you want.

I've been married for over forty years....

Many years ago I used to have a four post shaker rig....
Had nothing to do with shocks..........

Try it with shocks...it adds some pizazz...trust me on this one.

Do you load the car down with sandbags or something to simulate aero?

I'm curious too as to what you can really test with them. I've heard they are useful, and expensive. I can see shock development. Is it useful for determing suspension geometry? I would think it could be, but be very complex. Or is is more for loads and wear?

The seven “posts” are hydraulic cylinders. Four of them have flat pans the tires sit on and support the car. The other three are called the “aeroloaders” and attach to the sprung mass. Normally, two are mounted to the front of the chassis some distance apart while the third one is mounted at the rear on centerline. Loading on these cylinders is done to pull the car down, opposing the four wheel pans.

Cool. Thank you. (DOH! on my sandbag idea... I had some strange degree of freedom thought about needing more cylinders to simulate the tire loading)
