November 16, 2007 The team of Techno-Sciences Inc. (TSi) and the Smart Structures Laboratory
at the University of Maryland, College Park (UMCP), has been awarded a
NASA Phase I STTR contract to develop Adaptive Magnetorheological Isolators
(AMIs) to minimize vibration-induced damage of ground support electronics
(GSE) during rocket launches. Conceived by Principal Investigator, Dr.
Gregory Hiemenz of TSi, and Principal Specialists, Drs. Norman Wereley
and Wei Hu of UMCP, the AMIs will utilize innovative magnetorheological
(MR) fluid technology to optimally protect GSE located near a major rocket
launch from damaging vibration. Unlike conventional passive approaches
which can only be tuned for one excitation type and one GSE rack arrangement,
the AMI system will utilize internal motion sensors coupled with an on-board
microcontroller to provide automatic adaptation to the excitation as well
as the inertial properties of the GSE rack. Because of its adaptability
and optimal vibration isolation capabilities, the AMI system will significantly
reduce design and life-cycle costs and enhance equipment reliability. ![]() |
