Smart Materials and Structures Shock and Vibration Test Instrument for Real-Time Hybrid Substructuring of Advanced Marine Technologies
Abstract
Proposal AbstractThe University of Connecticuts (UConns) proposed procurement of three high forceelectrodynamic shakers, real-time target machine, data acquisition module, and essential sensinginstrumentation will significantly expand research capabilities for real-time hybrid substructuring(RTHS) investigations of complex marine systems for smart structure oriented shock and vibrationmitigation research. RTHS is a coupled numerical-experimental substructuring method thatinterfaces physical hardware components with numerical models of the remaining system in realtime.Current ONR funded research at UConns existing facility has shown that RTHS can capturethe inherent mechanisms of marine systems, such as fluid-structure interactions and system-levelresponse, often neglected in conventional component testing. Meanwhile, recent research on smartmaterials and smart structures has led to a variety of new concepts of mitigating shock andvibration effects. Developed in close collaboration with General Dynamics Electric Boat, theproposed upgrade to UConns facility will support the development of RTHS for complex marinesystems providing for high rate tests. The upgraded UConn facility will be used to conduct researchon systems with multiple transmission paths and high rates of loading, and will provide the Navywith an enhanced RTHS capability for conducting sophisticated coupled numerical-experimentsof complex marine systems in a laboratory setting. Specifically, several inter-related smartmaterial based system integrations, ranging from shock and vibration isolation, wave guiding, anddistributed sensors for system identification, will be examined, where the proposed new instrumentwill provide unprecedented capability of emulating excitations and environments of navalapplications.Leveraging the research and collaboration of the National Institute for Undersea VehicleTechnologies (NIUVT), our vision is to establish a research facility at UConn Avery Point thatwill enhance the performance and reduce costs of future submarines through accelerateddevelopment and implementation of advanced technology. UConns RTHS facility will be used toeducate the Navy and shipbuilding industry engineers on RTHS methods and will provide morerealistic loading scenarios for smart materials and structures with strong potential to improve thesurvivability, durability, reliability, and stealth of next-generation submarine designs.
