In　this　paper,　the　Shilnikov　type　multi-pulse　orbits　and　chaotic　dynamics　of　parametrically　excited　viscoelastic　moving　belt　were　studied　in　detail.　An　extension　of　the　Melnikov　method　was　utilized　to　analyze　the　global　bifurcations　and　chaotic　dynamics　in　parametrically　excited　viscoelastic　moving　belt.　The　theoretical　analysis　and　numerical　simulations　indicate　that　there　exist　the　homoclinic　bifurcations　and　the　Silnikov　type　of　multi-pulse　homoclinic　orbits　in　the　averaged　equation.
