The polar winding, as a kind of non-geodesic winding, is in a serious slippage trend. Based on the Theoretical Model of the filament winding, this paper outlines a kind of numerical methods for determining the stability condition of the polar winding on the composite pressure vessel with dished head. At last, through the providing some examples, this paper shows the stable trend on the dished dome during polar winding to optimize the design result.
