Rusty,
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
