Power flow transmission in a coupled flexible system with active executive elements

1 IntroductionIn mally engineering situations, machines are mounted on fiexible structuxes, e.g. shiPdecks, buiIding floors etc., which raises the problem of vibration isolation between vibrationsources and non-rigid fOundations. To handle such problems, one meets with a kind of coupleddynamic system[1I. Thc vibratory power flow transTIiltted in such systems has been wideIystudied and accepted to euluate the isolation effecti,.en..sf2.3J.Traditionally, a spring-t3Pe element is used as an …
