摘要

Instrumentation is needed to subject a wide variety of flexible systems to controlled vibrations in order to evaluate their performance when provided with appropriate passive and active vibration and noise control systems. The evaluation process will involve monitoring the vibration and noise radiation of these systems using a scanning laser vibrometer system to be acquired through this DURIP program. With such capabilities, it would also be possible to identify the sources contributing to excessive vibration and recommend the structural modifications necessary to meet the stringent constraints imposed on the operation of these systems. The proposed instrumentation will provide a general purpose facility for on-ground testing of critical systems such as the Viewing Imager/Gimbaled Instrumentation Laboratory (VIGIL) of the Ballistic Missile Defense Organization (BMDO). Such thorough on- ground testing is essential to ensuring satisfactory performance of these critical systems when deployed in space for autonomous operation.
