Vibration and Shock
All vibration and shock measurements in this section are made with a bare drive. The input for the measurements
are applied
to the normal drive mounting points unless noted otherwise.
12.1
Operating Vibration
12.1.1
Random Vibration
The drive is designed to operate without unrecoverable errors while being subjected to the vibration levels as defined
below.
The assessments are carried out during 30 minutes of random vibration using the power spectral density (PSD)
levels as follows.
No Errors: 0.4 G RMS, 5-500 Hz, flat PSD profile for each of the three mutually perpendicular axes.
No Data Loss: 1.2 G RMS, 5-500 Hz, flat PSD profile for each of the three mutually perpendicular axes.
No Data Loss: 1.5 G RMS, 10-300 Hz for each of the three mutually perpendicular axes.
Note: The specified levels are measured at the mounting points.
12.1.2
Swept Sine Vibration
The drive will meet the criterion while operating in the respective conditions as described below.
No errors: 1.0g @ 5-500 Hz sine wave, 0.5 octave/minute sweep rate
No data loss: 1.5g @ 5-500 Hz sine wave, 0.5 octave/minute sweep rate
12.2
Non-operating Vibrations
The drive will not sustain permanent damage or loss of recorded data after being subjected to the environments as
described below
12.2.1
Random Vibration
The test consists of a random vibration applied for each of the three mutually perpendicular axes. A time duration
of ten minutes per axis.
1.5 G RM S, 5-500 Hz, flat PSD profile.
12.2.2
Swept Sine Vibration
The test consists of a swept sine vibration applied for each of the three mutually perpendicular axes.
3.0 G 0-peak, 10 - 500 Hz sine wave, 0.5 octave/minute sweep rate.
12.3
Operating Shock
The drive will meet the criterion while operating in the respective conditions as described below.
No data loss: 15G, 11 ms duration, half sinewave shock pulse
No data loss: 60G, 2 ms duration, half sinewave shock pulse, read operation mode
