This article uses the basic theoretical formulas and numerical simulation methods of filament winding process,to study the influence of the fiber-width/diameter ratio and the pole/diameter ratio on the helical winding angle,to study the influence of the friction coefficient and the stable deviation angle on the non-geodesic helical winding angle.This enables engineers to quickly calculate the stable deviation angle based on the friction coefficient.Based on the applica-ble range of stable deviation angle for equal poles pressure vessels,provide route selection for the poles expansion winding.They are full geodesic poles-expansion winding,non-geodesic poles-expansion winding,and equal-angle poles-ex-pansion winding.The helical(geodesic)winding angle calculate based on the gradual expansion diameter,design the winding paths for full geodesic poles-expansion winding.The non-geodesic helical winding angle calculate based on the gradual expansion diameter and maximum friction coefficient,design the winding paths for non-geodesic poles-expansion winding.Calculate the stable deviation angle based on the helical winding angle corresponding to the gradually expansion diameter and the poles helical winding angle,and then calculate the friction coefficient,design the winding paths of the e-qual-angle poles-expansion winding by adjusting the friction coefficient method.
