Spectral Dynamics, Inc.

AGUAR ’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 controllimit 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 andor external drives.

The Shock and Bump (SD B) Series Machines are used to simulate and evaluate the design and destructive testing of components, circuits, hybrids, and complete assemblies. There are 5 standard shock and bump machine test systems available or we can also customize one to meet your needs. All our shock and bump machines are pneumatically powered shock testers for accuraterepeatable laboratory and production impact testing. With suitable pulse generators, these shock and bump machines can produce half sine, sawtooth, and square wave pulse shapes which meet the specifications of military, industrial, and individual test requirements. Generated waveforms comply with typical military specifications, including ISO, MILSTD-810, and customized method. They are used for both the commercial field and military applications; testing a wide variety of products from disk drives to wristwatches, and spark plugs to automotive sensors. DUT mounting table: The table is made from aircraft aluminum with high strength and uniformity but light weight. It is guided by 4 guide rods to keep high stability. High precision guide: Chromium plated high precision guide rod and sliding bearings assembly ensure the guide system a long life. Second shock preventing brake: After the first shock, the brake will be active to prevent an undesired second shock. Mounting Table Drive System: Adopting a high frequency velocity air cylinder with pilot actuated valve can ensure a short shock distance. This can result in the same shock terminal velocity, which is generated by 1.5 meters drop distance, a normal free drop shock machine. A precision displacement transducer, controlled by software, ensures the precise repeating drop height to get accurate repeatability of shock test. Shock absorption base: Shock absorption base is configured with a two-way damping device and large air bags. This can reduce the shock force transferring to the floor. No dedicated seismic base needed. Waveform Generators: Waveform generators can produce half sine, trapezoid, and sawtooth waves. Auto Shock control: ASK01 uses touch screen to control the shock activity. MIS02 is control and measurement system. Please refer respective spec sheets for further information. Expending features: Bump frequency and shock energy specifications can be expanded in a customized machine.

The Throughput Disk (TPD) features for Jaguar Systems provide an extra level of flexibility and convenience for users who are interested in continuously storing all of the acquired test data as quickly as possible The TPD data may be used for post-test data reduction by the Jaguar, converted to other formats or archived for long term storage.TPD Additionally, Jaguar TPD offers the unique capabilities of real-time processing and display features that allow you to fully document the test event as the data is being stored to the TPD hard drives. Depending on the application, you may store raw time history files or processed data to the TPD. The TPD feature are also supported for large channel count applications (greater that 500 channels) where a Jaguar system may be configured with multiple Acquistion & Control Peripherals (ACP). Each ACP supports independent TPD contrllers and drives for no reduction in test bandwidth or storage bandwidth. The multiple ACP's support simultaneous synchronixed sampling and storage for the full channel count. Throughput to Disk means streaming time histories to a disk drive located in the ACP. While acquiring data from sensors, producing resultant data, passing resultant data to the host, TPD also allows the parallel operation of storing time histories to disk. Implementation: With the addition of a proprietary Fast SCSI port added to the MDSP3 middle processor in the ACP, the disk drives, up to six, 18 Gbytes ea. store up to 98 channels of data sampled up to 25, 600 times sec each. Other combinations to 51.2k are furnished. The data format is extremely dense for optimum efficiency. The Drives: The large ACP shown at left may house 1 or 2 drive(s) internally and up to 4 additional drives in the caddy shown on top of the ACP. The external drives may be swapped, allowing rapid expansion for sequential tests, without waiting to download the disks to the host. Playback: Data stored on the TPD may be selected as the source for the data stream fed to a variety of application packages. The analysis processes offered by those sw packages can then be performed upon the TPD data. Applications Supporting TPD: MISO and MIMO Random support time history storage and permit playback of time histories via the Rand2 disk om Analysis feature. Signal and Transient Capture support time history storage and play back. In addition both may playback files from MISO and MIMO Random, with analysis. Sine Analysis will play back Signal data from TPD, allowing Tracking Filtered analysis of raw time histories while preserving the original time history. MISO Sine Control will store and analyze complex data rather than time histories. This permits H(f) pairings to be re-established for additional analysis of original data. Long Term Storage: TPD files are very dense and must be converted to an open architecture for post-test use. JAGUAR permits the storage of the dense file to the host as intermediate storage. The user may also choose to translate and store, at the push of a button, in I-deas™ATI format, MatLab ASCI or MatLab Binary formats to the host disk or to optional fast SCSI drives that can be removable.
