Coupled dynamic systems and Le Chatelier’s principle in noise control
G. Maidanik, K. J. Becker · The Journal of the Acoustical Society of America · 2004
Investigation of coupling an externally driven dynamic system—a master dynamic system—to a passive one—an adjunct dynamic system—reveals that the response of the adjunct dynamic system affects the precoupled response of the master dynamic system. The responses, in the two dynamic systems when coupled, are estimated by the stored energies (Es) and (E0), respectively. Since the adjunct dynamic system, prior to coupling, was with zero (0) stored energy, E0s=0, the precoupled stored energy (E00) in the master dynamic system is expected to be reduced to (E0) when coupling is instituted; i.e., one expects E0
