Methods for characterizing vibration of a rack structure

摘要

A system for characterizing vibration of a rack structure having at least one hard disk drive disposed therein and a vibration exciter operatively associated with the rack structure includes one or more computers. The one or more computers are configured to command the vibration exciter to provide vibration input to the rack structure and to command a plurality of reads from the at least one hard disk drive such that, for each of the plurality of reads, data stored on the at least one hard disk drive is retrieved from the at least one hard disk drive. The one or more computers are also configured to obtain read rate information related to the plurality of reads and to identify at least one resonant frequency of the rack structure based on the read rate information.

1. A method for characterizing vibration of a rack structure comprising:
by a processor,
commanding a vibration exciter operatively associated with the rack structure at a first location to provide step-wise mono-frequency vibration input to the rack structure,obtaining response data to the vibration input from (i) an accelerometer operatively associated with the rack structure at the first location, and (ii) another accelerometer operatively associated with the rack structure at a second location,identifying at least one resonant frequency of the rack structure based on the response data from the accelerometers, anddisplaying the at least one resonant frequency.
