Active contorl of coupled wave propagation and assocated power in fluid-fillecd elastic long pipes

摘要

The active control of totla power flow in oth media of fluid-filled elastic pieps by structurally mounted actuators and senwsors is analysically and experimentally studied.HTe ocnstorl paramdign used was the feedformward LMS technique.HTe results indicate that for a 3130 system,high attenuatin of total powr is possible fora substantial range of lwo rfrequencies.the use of structural acturators and sensors for reducign interior ocupled fluid power is thus validated.
