This　paper　focuses　on　the　multi-pulse　orbits　and　chaotic　dynamics　of　the　six-dimensional　nonlinear　system　for　the　composite　laminated　piezoelectric　rectangular　plate　using　the　theory　of　normal　form　and　the　energy-phase　method.　Taking　into　account　that　the　averaged　equation　has　a　double　zero　and　two　pairs　of　pure　imaginary　eigenvalues,　we　use　the　theory　of　normal　form　to　simplify　the　six-dimensional　averaged　equation　to　a　simpler　normal　form.　The　energy-phase　method　is　to　be　extended　to　study　the　dynamical　characteristic　of　the　six-dimensional　nonlinear　system.　The　global　theory　analysis　indicates　that　there　exist　the　homoclinic　bifurcation　and　Shilnikov　type　multi-pulse　jumping　chaotic　dynamics　in　the　system　under　the　small　perturbation.　In　order　to　illustrate　the　theoretical　predictions,　the　Runge-Kutta　algorithm　is　used　to　perform　numerical　simulation.　The　results　of　numerical　simulations　also　demonstrate　that　the　jumping　phenomena　of　orbits　can　occur　in　the　composite　laminated　piezoelectric　rectangular　plate.　Copyright　©　2009　by　ASME.
