Active - definitely, Lotus - probably, but it must have been after 1989. My best guess would be the Lotus 107 - one of them, anyway.auteoch wrote:Lotus active suspension?
That would be for the WGP system, not for the system shown, I think. The Dernie suspension has been described by Scarbs, who obtained his information from Dernie's patent (US 4861066).matt21 wrote:BTW Frank Dernie is still holding a patent on the active suspension.
Do you have the book's name by any chance?tuj wrote:there is a book on the FW14b that had quite a bit of technical information about how the active suspension worked.
Holy smoke, 530 USD for 128 pages? Can anybody afford this book here?
My guess would be that the book conveys less technical detail about the suspension than Scarbs' article.MadMatt wrote:Can anybody afford this book here?
That might be true of the WGP system, but it was not a statement of the microprocessor capacity available at the time. Scarbs quotes that the WGP system iterated at 64 per second. Yet in 1984, the Lotus system iterated at 1 millisecond, executing around 2K operations per iteration. The TMS320C20 was available at the time, executing most operations in 200 nanoseconds. By 1987 the TMS320C25 was available with a better architecture and an increased overall capacity....tuj wrote:well one of the thing the books talks about that is not mentioned in the Scarbs article is the limitations and work-around for the microprocessor capacity of the early 90's...
Found it here, but don't if the website works, was looking for a PDF but nothing :/ http://www.andymathews.com/bookstore_williams.phpMadMatt wrote:Holy smoke, 530 USD for 128 pages? Can anybody afford this book here?
