I am by no
means an expert in vibration analyses, but I have been witness to some unusual
vibration events involving steam turbines. In one event a piece
of dismantled turbine (60,000 Lb) was set on the independent
foundation of an operating steam unit. The shaft vibration on several of
the bearings went down. Everyone watching this thought "Hay this ant
bad" so when they decided to temporarily store another piece of the
dismantled turbine weighing in at 45,000 Lb on the same foundation, no one
gave it a second thought until the vibration on the in service turbine jumped up
to almost twice what it was previously running. So I guess what I was
trying to say was that stationary weight can have as much effect on the
vibration as can the rotating weight
Hi
Bob,
Expect the
unexpected :-) One of the reasons I'm trying not to get too involved
with this problem, is that I KNOW how much time I'll eventually spend on
it. It will be an interesting project, and worth the time, but I just
can't let myself get caught up in it now. Once the RV-8 is
flying, I can go into mad scientist mode to see if there's some solution to
this. I've already thought of way too many experiments already.
Must resist....
Rusty (RV-8
first, RV-8 first, RV-8 first...)
