| Abstract: | In gernal,mobility power?flow analysis has been used for the analysis of the vibration response and transmission between element of the coupled structures.The power?flow technique is extended to two?dimensional thin platelike coupled stuctures which are orthognally joined along a common edge and excited by a transvers point harmonic force.Then,power?flow model of substructural components of the coupled plates is given.By extended mobility functions,the expressions which indicates the input power of flexible wave of source plate and the trandmitted power of receiver plate of the coupled structures are derived.Thus,the resonant model response of the coupled structures is accurately determined. |
