| Abstract: | The vibration of a composite beam, embedded with piezo-electric film, is analysed in the paper, Hamilton principle is made in use to analyse the coupled effect between piezo-elec-tricity and structure deformation,considering the influence of electric field on deformation, the e-quation of motion of a composite beam is derived. A simply supported composite beam is taken as an example. The good conformance between the results of numerical analysis and test verifies the correctness of the analysis procedure. |
