Six-Degree-of-Freedom Shake Table and Instrumentation for Real-Time Hybrid Substructuring (RTHS)
Abstract
UConn’s proposed procurement of a six-degree-of-freedom shake table, upgraded controlsystem, data acquisition module, and other essential instrumentation will significantly expandresearch capabilities for real-time hybrid substructuring (RTHS) investigations of complexmarine systems with multiple vibration transmission paths. RTHS is a coupled numericalexperimentalsubstructuring method that interfaces physical hardware components withnumerical models of the remaining system in real-time. Current ONR funded research atUConn’s existing facility has shown that RTHS can capture the inherent mechanisms of marinesystems, such as fluid-structure interactions and system-level response, often neglected inconventional component testing. Developed in close collaboration with General DynamicsElectric Boat, the proposed upgrade to UConn’s facility will support the development of RTHSfor complex marine systems with multiple transmission paths, such as piping systems and largespan multi-support structures, to reduce costly conservatism earlier in the design process. Theupgraded UConn facility will be used to conduct future research on systems with multipletransmission paths and will provide the Navy with an enhanced RTHS capability for conductingsophisticated coupled numerical-experiments of complex marine systems in a laboratory setting.Our vision is to establish a research facility at UConn that will develop and transition RTHScapabilities to the Navy laboratories and shipbuilders, such as General Dynamics Electric Boat.UConn’s RTHS facility will be used to educate the Navy and shipbuilding industry engineers onRTHS methods to facilitate a smooth transition of RTHS for real world marine applications ofvibration control and structural acoustics. It is expected that this RTHS capability will providemeaningful gains in accuracy and potential cost savings for qualification testing of marineequipment and systems.
