Hardware and mechanical test items and criteria
Category: Machinery
Subcategory: Machinery
Item:
1) Static pressure test:
DKBA1109
(TL=Wt*(S-1)* (k)*(9.8 N))
for 2h, of which:
TL: It is the pressure value applied to the equipment, but N (Newton);
Wt: the weight of the package itself, in Kg;
S: the number of identification layers of stacking;
K: compensation coefficient, LEVEL I=59
2) Package drop
DKBA1109
LEVEL 1
weight M (kg), drop height (mm) //mm //
20=<M<30 800mm
30=<M<40 600mm
40=<M<50 500mm for
each specified surface, The corners and edges each drop once;
6 each side: 6 outer surfaces of the package, and the packaging with the shipping package. The
number of drops: each time;
3) Random vibration

DKBA1109
18G
shock wave half sine wave, peak acceleration: 300m/s2 (s squared); pulse width 6ms,
shock axis: 6 directions;
number of shocks: 3 times in each direction;
5) Packaging collision
DKBA1109
10G
collision waveform half sine wave, peak acceleration 180/s2 (square of S), pulse width 6ms,
impact axis: 6 directions;
collision test: 100 times in each direction;
6) Working vibration
5~500HZ, 0.27Grms, 3axes, 10min/axies
PSD: [email protected](g square)/HZ
[email protected](g square)/HZ
[email protected](g square)/ The HZ is
placed on the bracket to simulate the actual installation method; the
read and write speed of the SAS/FC hard disk in the test state is not less than 50% of the read and write speed in the normal working state of the
hard disk ; the SATA hard disk is 30%;
3) Random vibration
DKBA1109
