In　this　paper,　the　Shilnikov　type　multi-pulse　orbits　and　chaotic　dynamics　of　parametrically　excited　viscoelastic　moving　string　are　studied　in　detail.　Using　Kelvin-type　viscoelastic　constitutive　law,　the　equation　of　motion　for　viscoelastic　moving　string　with　the　external　damping　and　parametric　excitation　is　given.　The　four-dimensional　averaged　equation　under　primary　parametric　resonance　is　obtained　by　directly　using　the　method　of　multiple　scales　and　Galerkin＇s　approach　to　the　partial　differential　governing　equation　of　viscoelastic　moving　string.　The　Shilnikov　type　multi-pulse　chaotic　motions　of　viscoelastic　moving　string　are　also　found　by　using　numerical　simulation.　A　new　phenomenon　on　the　multi-pulse　jumping　orbits　and　a　new　strange　attractor　are　observed　from　three-dimensional　phase　space　for　the　first　time.　Copyright　©　2005　by　ASME.
