JAGUAR - Random Control
Random vibration testing is
intended to verify that the device under test will withstand the
vibration and perform to specifications afterward. Test accuracy
is expected. Accuracy of signal generation, signal measurement,
filtering and control algorithms are required to ensure accurate
test results.
JAGUAR ’s hardware superiority permits the control scheme to
deliver the most accurate and rapid closed-loop control
available.
 | Loop times are well under a second with
virtually no negative impact from the addition of control
channels.
| 98 control/limit channels assure that even
the largest, most complex structure can be controlled. Limit
channels further enhance large structure control and
accuracy. Each limit channel may have its own reference
profile.
| The ability to view all measurement
channels, limit channels, H(f), as well as computed spectra
in real-time and simultaneously means you never have to
wonder if your data are good. You can also examine all
criteria for test accuracy while the test is underway, i. e.
, each PSD for each control channel that comprises the
aggregate control, each limit channel PSD as well as limit
profiles, H(f)that are composed in part or whole by control
channels also engaged in averaged control, phase, coherence,
and more.
| Random signal generation using a 48 bit
random number sequence means JAGUAR produces the “most
random ”test ever produced by a digital control system.
Coupled to the most advanced phase randomization techniques
you are assured of a very accurate test.
| JAGUAR ’s patented Adaptive Control
Algorithm gives you peace of mind knowing that non-linear
structural problems will be controlled more rapidly and more
accurately than with any other approach currently available.
All of these data would be of no value if the software
were difficult to use.
For 10 years customers the world over have rated Spectral
Dynamics ’ user interface the easiest to use and the most
capable.
Throughput to Disk Control
An optional feature for JAGUAR is the ability to add
throughput disks to each Acquisition and Control Peripheral
(ACP). Disk capacity from nine (9)GBytes up to more than
thirty (30)GBytes is available. As many as 6 drives per ACP
are permitted. MISO Random permits time data to be streamed
to the throughput disks during control so that a permanent
record of the test and all measured responses may be stored
for post test analysis or archived. Each ACP may have
internal and/or external drives.
Throughput disks are controlled via the SCSI port
attached directly to the MDSP III inherent to each ACP.
Optional throughput control software that operates under the
Random application provides seamless operation during a
control test so the operator need not contend with decisions
about throughput disk operation during a closed-loop test.
Playback of throughput data
may be used as an opportunity to reprocess the time data
with different transfer function pairings or averaging
choices from the control scheme. This significantly enhances
the analysis of post-test results. |
