Hi guys, I hope we got some expert out here for vibration profile problems. I have a device that need to be on a shaker table but I need to "find" its profile to see if the shaker table can actually run this experiment. The Shaker table is Unholtz-Dickie system SA30-560B and I have data of this table's profile in Acceleration (g PK) vs Frequency (Hz). My device with fixture weights 23.5lbs, and I need to run it between frequency of 10 to 500 Hz with 30.59g force, this is a long life test. Can someone help me on finding the X, X2, X3? Also that ASD stands for what? I can't figure out what that stands for, but the table's profile has in Acceleration of g-force Peak vs Frequency instead of ASD vs. Frequency.
