RE: Floor vibration design

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Well, it's the max. velocity of a harmonically vibrating doo-hickey, isn't
it? If my elementary mech. vibrations knowledge is still somewhat current, I
believe it occurs at "X=0" on the sinusoidal plot.

Oh, and a "micro-inch" is one-millionth(!) of an inch.

We have some plans that specify that the floor system shall
be designed for a "max velocity of 4000 micro-inches/sec".
What does this mean and how do you accomplish this?
