The　researches　of　global　bifurcations　and　chaotic　dynamics　for　high-dimensional　nonlinear　systems　are　extremely　challenging.　In　this　paper,　we　study　the　multi-pulse　orbits　and　chaotic　dynamics　of　an　eccentric　rotating　composite　laminated　circular　cylindrical　shell.　The　four-dimensional　averaged　equations　are　obtained　by　directly　using　the　multiple　scales　method　under　the　case　of　the　1:2　internal　resonance　and　principal　parametric　resonance-1/2　subharmonic　resonance.　The　system　is　transformed　to　the　averaged　equations.　From　the　averaged　equation,　the　theory　of　normal　form　is　used　to　find　the　explicit　formulas　of　normal　form.　Based　on　the　normal　form　obtained,　the　extended　Melnikov　method　is　utilized　to　analyze　the　multi-pulse　global　homoclinic　bifurcations　and　chaotic　dynamics　for　the　eccentric　rotating　composite　laminated　circular　cylindrical　shell.　The　analysis　of　global　dynamics　indicates　that　there　exist　the　multi-pulse　jumping　orbits　in　the　perturbed　phase　space　of　the　averaged　equation.　From　the　averaged　equations　obtained,　the　chaotic　motions　and　the　Shilnikov　type　multi-pulse　orbits　of　the　eccentric　rotating　composite　laminated　circular　cylindrical　shell　are　found　by　using　numerical　simulation.　The　results　obtained　above　mean　the　existence　of　the　chaos　for　the　Smale　horseshoe　sense　for　the　eccentric　rotating　composite　laminated　circular　cylindrical　shell.
