59 -- DIGITAL VIBRATION CONTROL SYSTEM SOL DAAE30-97-R-0805 DUE 072497 POC Judy Szabo, AMSTA-AR-PC-H/BLDG #9 (201)724-5373 WEB: Click here to see more information, http://procnet.pica.army.mil. E-MAIL: Click here to contact the Contract Specialist via e-mail, jszabo@pica.army.mil. Sources are sought for two Digital Vibration Control Systems, Sixteen Channel, Spectral Dynamics P/N 2550B or equal, in accordance with ARDEC salient characteristics. The systems shall have features for sine, random, mix mode (random on random, sine on random) classical shock, shock response spectrum, pyrotechnic shock, simulated gunfire vibration and control of electrodynamic vibration systems. The systems shall be constructed on a modular basis using standard production assemblies and subassemblies and shall include a 17" monitor and color printer. Some of the salient characteristics are as follows: greater than 50kHz sample rate per channel for all active channels, capable of sine sweep tests from 1 Hz to 10,000 Hz; frequency sweep selectable in terms of rate or duration -- Lincar .001Hz/min to 18,000Hz/min -- Logarithmic: 0.1 octaves/min to 8800 octaves/min; test profiles -- a maximum of 90 frequency segments may be defined; test duration: maximum 10,000 sweeps or 999 hr, 59 min, 59 sec (hhh,mm,ss) -- unlimited test; output level: automatically controlled with user defined max 0 to 10 volts; output dynamic range of 80dB or greater; harmonic distortium -- less than -75 dB at full test level; control channels -- sixteen input channels, (expandability to 32 channels) with maximum input of +/- 10 volts; all input channels must be able to be displayed simultaneously during a test; measurement -- parallel digital rms, peak amplitude and tracking filter level detection for each channel processed.
