Vibration - Seagate Medalist 6540 Product Manual

Medalist 6540, 5130 and 3220 Product Manual, Rev. A
1.8.5.1 Operating shock
These drives comply with the performance levels specified in this docu-
ment when subjected to a maximum operating shock of 10.0 Gs (based
on half-sine shock pulses of 11 msec, as specified in MIL-STD-202F).
Shocks are not to be repeated more than two times per second.
1.8.5.2 Nonoperating shock
The nonoperating shock level that the drive can experience without
incurring physical damage or degradation in performance when sub-
sequently put into operation is 75 Gs (based on nonrepetitive half-sine
shock pulses of 11 msec duration) or 150 Gs (based on nonrepetitive
half-sine shock pulses of 2 msec duration). Shock pulses are defined by
MIL-STD-202F.

1.8.6 Vibration

All vibration specifications assume that the drive is mounted securely
with the input vibration applied at the drive mounting screws. Vibration
may be applied in the X, Y or Z axis.
1.8.6.1 Operating vibration
The following table lists the maximum vibration levels that the drive may
experience while meeting the performance standards specified in this
document.
5–22 Hz 0.020-inch displacement (peak to peak)
22–350 Hz 0.50 Gs acceleration (zero to peak)
1.8.6.2 Nonoperating vibration
The following table lists the maximum nonoperating vibration that the
drive may experience without incurring physical damage or degradation
in performance when put into operation.
5–22 Hz 0.10-inch displacement (peak to peak)
22–350 Hz 5.0 Gs acceleration (zero to peak)
