active suyspension design project for military
(OP)
i've done a bit of searching and found this (thread800-102241) thread on active suspension systems, namely the one from Bose.
my research group works on electromechanical actuators (robotics), which is essentially what the damper is replaced with, and are working on a proposal with Lockheed to develop more space and energy efficient active suspension rotary actuators for military vehicles (which actually have the absolute most to gain from such systems). i typically work on decision making control algorithms which, in this case, would be responsible for how successful the system is in filtering out harmonics. But im trying to get a feel for what has already been done. I know formula 1 has been used these systems in the past (present?), as they should be due to the immense performance potential... but i cant seem to find anytihng on them. i would think there would be a patent at the very least...
If anybody knows of any database, paper, patent, anything that has already been done along these lines please let me know... im chiefly interested in the mathematical framework that details the sensing/actuation but anything along these lines i would definitely be interested in seeing. I'm particularly interested in F1 documentation because they have so much money to spend and (thus) are the only application in which an active suspension design has been fully developed and integrated. cheers and thanks for any help! really is interesting stuff, im lucky to get to be working on it..

Moog electrovalves were an integral part of the active suspension designs. Here is a press article from them. You may include them in your inquiries:

"Active off-road suspension" is kind of a misnomer. If speed is involved, you will have more than harmonics to deal with.

There's plenty of literature out there on the Lotus system, which was the one fitted to the F1 cars. Williams were using a 'slow' active system based on work by AP (that came from military vehicles too!). ISTR a lot of the papers on the subject were IMechE and FISITA rather than SAE.
