In　this　paper,　the　multi-pulse　orbits　and　nonlinear　dynamics　of　an　eccentric　rotating　composite　laminated　circular　cylindrical　shell　clamped　along　one　generatrix　subjected　to　the　lateral　and　temperature　excitations　are　studied　in　detail.　Based　on　the　two-degree-of-freedom　non-autonomous　nonlinear　equations　of　the　eccentric　rotating　circular　cylindrical　shell　under　the　case　of　1:2　internal　resonance,　we　obtain　the　four-dimensional　nonlinear　averaged　equation　by　using　the　method　of　multiple　scales.　According　to　the　averaged　equation,　we　use　the　theory　of　normal　form　to　find　the　explicit　formulas　of　normal　form.　Then,　the　multi-pulse　global　heteroclinic　bifurcations　and　chaotic　dynamics　for　the　eccentric　rotating　circular　cylindrical　shell　are　analyzed　by　the　extended　Melnikov　method.　It　is　found　that　there　exist　the　multi-pulse　jumping　orbits　in　the　perturbed　phase　space　of　the　averaged　equation　through　the　analysis　of　global　dynamics.　At　last,　in　order　to　describe　the　nonlinear　dynamic　responses,　bifurcation　diagrams　and　the　three-dimensional　phase　portrait　are　given,　and　we　find　the　chaotic　motions　and　the　Shilnikov　type　multi-pulse　orbits　of　the　eccentric　rotating　circular　cylindrical　shell　by　the　numerical　simulation.　It　can　be　concluded　that　there　exists　the　chaos　for　the　Smale　horseshoe　sense　for　the　eccentric　rotating　circular　cylindrical　shell.　Therefore,　it　is　feasible　to　study　the　nonlinear　dynamics　of　an　eccentric　rotating　composite　laminated　circular　cylindrical　shell　system　based　on　the　theoretical　method　©　Proceedings　of　the　26th　International　Congress　on　Sound　and　Vibration,　ICSV　2019.　All　rights　reserved.
