[sci.space] Dahl's friction model

lvron@earth.lerc.nasa.gov (Ronald E. Graham) (02/07/91)

I'm trying to find references to the above subject.  Here is what little
I know: Dahl worked at the Aerospace Corp. when he put out some his references
to modeling of Coulomb friction for aerospace systems, particularly engine
gimbals and gyros.  Can anybody help me locate references?

Thanx in advance.
